default variant ordering is by order added to the database, not alphabetical (and not using POS), even in X-Cart variant administration
That makes sense, Jon. For my store, we were very organized on the way in, and used a spreadsheet and csv import to propagate products -- so our admin section looks quite organized and in perfect order. But in my test store, it's a freaking mess! So I am able to test both ways.
I always suggest a csv import, for products anyway!
