@norman187 - although well meaning, this "solution" you offer is totally counter-intuitive to what ANY reminders/todo/list app should be without any "hacking" or arduous "work arounds" having to be done by the user. If you WANT to enter a date, or a time, or a set of parameters to any or all tasks or reminders on the list, you certainly should be able to, but if you DON'T WANT to add all that crap, you should be able to just type in 3 or 5 or 50 tasks into the list and then re-order them any way YOU want to by simply hitting an "edit" button and then dragging them up or down to create the prioritized list that meets YOUR needs.
The fact that Reminders in iOS6 has multiple pages of lists is stupid and so hard to use (especially on the iPhone, not as bad on the iPad and iMac versions). And this part of the design is a major reason why a LIST itself doesn't have a simple sort feature for the tasks. Since Apple set it up to have multiple lists and gave the sort feature away to be able to sort the lists (how useless is THAT?), you apparently can't then also add a sort featrue to each list and sort the individual tasks. A Reminders/ToDo app needs ONE list with multiple ways to designate if a task is personal or work or family, etc, and a way to sort or re-order individual items (tasks/reminders) to the user's preference. You want a list just for gorceries, you say? You want a separate list for homework (or whatever)? That's where SUB-TASKS comes in... you should be able to create a task with a title that indicates the contents of the list (shopping list, homework for math, etc) and then create sub-tasks that are the new, separate list for that category. EASY!
Previous commenters are correct - repeating reminders don't stay in any order, and once a reminder/task passes it's assigned date/time without being accomplished, the date/time feature becomes useless (unless you go back in and re-assign a new date/time, whcih you would have to do to EVERY task EVERY DAY if norman187's idea was to be put into practice). Very few people get every task on thier reminder list done evey day (congrats to you, whoever you are) so this idea of re-assigning new dates/times to every task every day just to keep them in a sorted order that makes sense to the user is preposterous. And sub-tasks is a basic requirement of any decnet ToDo or Reminders app as well, as multiple commenters have stated.
To anyone on this thread who is actually holding out hope that Apple will revise Reminders to be a useable task list with an easy, intuitive sort feature, sub-tasks, and all the other stuff we all need in our Reminders/ToDo list apps, you should move on and find something else. Several commenters above have given ideas for other good reminder apps, and you should try one or more of those. I really believe that Apple has purposefully designed thier Reminders app to be what it is and no more to 1) fill one niche of the reminder market, and 2) to make room for other apps that are already out there and doing everything we need. Apple Reminders is to task list apps what Apple Maps is to map apps... they have a few super cool features and yet fall short on most common stuff you need to live everyday life. Since you already have/use Google Maps app instead of using Apple Maps, you need to do the same thing for your Reminders app... go find a better solution outside the native.
MY FAV Reminders/ToDo app is - Todo (by Appigo). It does EVERYTHING 99% of users would even need a reminder app to do, it is beautiful, intuitive, loaded with features, and comprehensive in its approach to helping me stay on track. It is NOT free, which is why it is so good. Having a top-tier reminders/todo app is so important to me that I gladly paid for the full version once I saw how good the app was from the free trial. It has everything Apple Reminders has and then 100 other features that blow Reminders away. It is, IMHO, the very best of many good reminder/todo/task list apps out there. You really should check it out.
I have resigned myself to the reality that this is the answer... downloading (buying?) another reminders/todo app and shuttering Apple Reminders away in a sub-folder, never to be seen again.
