pick up schedtool, and these are the choices it gives:
-N for SCHED_NORMAL
-F -p PRIO for SCHED_FIFO only as root
-R -p PRIO for SCHED_RR only as root
-B for SCHED_BATCH
-I -p PRIO for SCHED_ISO
-D for SCHED_IDLEPRIO
then for example to start up something as SCHED_IDLE:
schedtool -D -e ./somecommand.sh
