Just comparing this theme's css with the 960.gs's css and it looks like the code for the clearing and clearfix has changed.

Here is a commit messages from 960.gs:
Commit: 23a1b4934cf03a530a42
Changes to make clearfix more bulletproof. Also, makes .container_xx (12, 16, 24) automatically clear floats inside of them. Removed extraneous clearing

's in demo HTML pages.

Hope that helps,
-Glenn
