This may not answer your question, but
apt-get install rtirq-init
might be all you need to do in order to get the interrupt priorities set
and sorted out for your purposes (well, for sound
recording/processing/playback it usually works reasonably well).
Even if not, taking a look at what the rtirq service script does might
give you good ideas.
