Coursemanage and iTunes U show different order

I have a course I have created in iTunes U Course Manager, "Intro to JavaScript - Google Docs Spreadsheet". I have all the posts in order in the CourseManage but when they are published as the course in iTunes U the posts are out of order.

Course: http://itunes.apple.com/us/course/intro-to-javascript-google/id502871512

How can I get the order to be correct in the course in iTunes U when I download the course to my iPad?

Thanks
