It was not sorted by team number, team location or team name. I tried plotting all three to see if there was a pattern, and I didn't find one. Someone else posted that it wasn't based on registration date, based on how the last registrants are distributed.

So unless they found some other sorting mechanism, maybe based on some performance criteria such as quals ranking, it appears to be a random assignment. Random would give you strings of teams all assigned to the same division, such as 236 through 271 all being in Curie.
