Random seeding was the first implementation, more than a year ago [it means that it would be very easy to add it again]. The default "sorted by BKR and similar average BKR in all sections" approach has been implemented on GothicInventor's request [very good idea, I must say, originally from Caissus] and is currently used for all tournaments. And it's not hard to plug in more algorithms.
So, it seems to be a new option on Define Tournament page, eh? :-)
