Considering how at least one (my :( ) buildbot happily used 3.1 for py -3.10, we might want to put 3.10 at the end of the list here.

Hm... Before 1037ca5 this said (3.9 3.8) so I assume the intention was to try the latest first. Maybe @zooba can help out? (Steve, why would an older py -3.10 on Windows 8.1 find 3.1? (Yes, 3.1 was installed there; and 3.10 wasn't. But it feels like an argument parsing issue in launcher.c.)
