In the smart playlists, the order is the order that it fetches it from the database, which, for gdbm, is whatever order it feels like.
If you are serving from a machine with some horsepower, you can go into the top of db-gdbm.c and change “WANT_SORT” from 0 to 1.
That will sort stuff by artist, album, track. But it pulls the entire database and does an insertion sort on it, so it will only work on a real machine with some ram, not a NSLU2.
