I don't use adaptive scoring, but I use the usual scoring stuff all the time in nnimap groups. I use topic mode in the groups buffer. I also use expiration, but auto-expire and total-expire, in nnimap groups. In this case the messages (articles, gnus calls them) are actually removed from IMAP server. The only funny part is that expiration happens when exiting a group, so it's somewhat async and in arrears, but in terms of keeping messages around for a while and then pruning, it works for me.
