I just spent a bunch of time with Apple and have solved my similar problem. A week ago, iCal and my iPhone calendar stopped syncing. My assortment of iCal calendars were gone from iCloud, so that was the problem (not phone to iCloud). After much de-selecting and re-selecting, I realized that all my important calendars were @me.com type. I tested the iCloud calendars, and they functioned perfectly. Apple explained a simple way to migrate the @me.com calendars to iCloud:
Create a new iCloud calendar File > New Calendar > iCloud
Name the calender
Right click the old @me.com calendar and choose Export. Desktop is a good destination.
Drag the exported calendar from your desktop to the new iCloud calendar
iCal should show duplicates of all events in the @me.com calendar.
De-select the @me.com calendar. The duplicates will disappear.
Repeat with all the @me.com calendars and abandon this antiquated list.
Rejoice in your shiny new list of iCloud calendars that shows up everywhere it is supposed to.
There must be a lot of people out there who still have @me.com calendars, so I hope this info reaches them before they all spend time and money with Apple trying to sort it out.
