To optimize finding the right version in the fixed-in-version drop down list for our purposes, I sorted the list by version numbers.

Intention: Sometimes it happens that we must provide a new patch for an old project version and with normal installation that patch is the topest entry in the version list but this is confusing, because for daily bussiness the handler usually select the topest version in list because he thinks this will be the next release where his actual bug is fixed.

My fix would be in core\version_api.php:
Replace in methods version_get_all_rows() and version_get_all_rows_with_subs() "ORDER BY date_order DESC" with "ORDER BY version DESC"

Maybe this is useful for you too.
