Just wanted to follow this up with the solution. After chasing dead ends for awhile (and learning more about the inner workings of ListCollectionView,) I finally realized that (duh) I wasn't calling refresh() on the view after setting my sorts! I'm using Uday Shankar's excellent CGrid component, and I thought there was a sort applied inside that, but I was wrong. That's what I get for coding at night I guess :)
Still having problems with seeing framework source in the debug view, but I'll post that in another topic.
