I personally can't see why it wouldn't scroll the last few menu's with the scrollbar. I'll look into the code properly and see if I can fix it on PC. I'll post back with the results for you bud. If anything, was one of the best World At War Menu's, nice to see it show up on BO2. I did actually recreate this but without the overflow fix. Maybe that menu style might work here.
EDIT: Inbox me Liam, might have the source code laying around somewhere.
