It couldn't be done without modifying the code itself, but I can think of
two possibilities:
A) After finding the file, generate a random number from 1-5, and use this
to determine whether to play this song, or find another: if the number is <=
the rating, play the song, otherwise find a new file and repeat the process.
B) Create five playlists, each with a different priority, and then add each
playlist to a metaplaylist, such that the playlist with five-star items is
added five items. Then, each time, select a random playlist from the
metaplaylist, and select a random file from the playlist.

Of course, both of these suggestions involve modifying the rockbox code
(possible drastically, I don't know), so they aren't really that helpful.
Sorry.
