So now that there is a "Select a theme" drop down list at the top of the Theme Customizer screen, any chance that you can force that list to sort alphabetically? I realize the problem is not specific to Theme Customizer, of course. The normal way of setting themes from the desktop is also out of order. It used to be in alpha order back in PR1.1, but has been sorted in an arbitrary order in PR1.2 and PR1.3. It would be appreciated if you could find a solution.
