Circuit switch fallback means of changing from packet switching to cs because of network coverage(changing 3g in urban to 2g in rural areas).

CS Fallback means that the EPC is telling the RAN that CSFB must be performed, presumably because the UE is initiating or receiving a circuit voice call.

Now coming to your question, I believe that cs-fallbackhighpriority is intended for use in emergency calls that need to be sent to the UMTS network to be handled (though not 100% sure)
