[misched] Fix a truncation issue from r263021.

Browse Source 
The truncation was causing the sorting algorithm to behave oddly when comparing
positive and negative offsets.  Fortunately, this doesn't currently happen in
practice and was exposed by a WIP.  Thus, I can't test this change now, but the
follow on patch will.
