Actually, I believe this patch will have no effect at all (because its
sorting is overridden by the subsequent sorting that takes place in
`package-process-define-package`).

This said if this dir-sort usually puts older versions first, then maybe
it's a good change: it increases the chance that the "sorted insertion"
used in `package-process-define-package` the can be done in O(1), so it
might speed this up a tiny-teeny bit, sometimes.
