I am not familiar with SCHED_RR, but with FX priority scheduling your priority does not change. If you do an IO you return at the same priority, if you exhaust your time quanta, you return at the same priority. With TS your priority changes depending whether you give up the CPU voluntarily (IO for example) or exhaust your timeslice. With FSS your priority is adjusted so that you will get your fair share of resource.
