Victor,
AFAIR, with PIPQ, classification is performed on per-DLCI basis (DLCIs
are assigend to priority queues).
When you enable PIPQ and FRF12 at the SAME time, the dual FIFO
is replaced with PQ. Fragmented and non-fragmented packets may go
to the same queue, if they belong to the same DLCI.

FR PIPQ works with or without Frame Relay traffic shaping (FRTS) and FRF.12.
The interface-level priority queueing takes the place of the FIFO queueing
or dual FIFO queueing normally used by FRTS and FRF.12. PVC priority
assigned within FR PIPQ takes precedence over FRF.12 priority, which means
that all packets destined for the same PVC will be queued on the same
interface queue whether they were fragmented or not
