Peter, The MQMD-Priority is used by MQ to decide the order in which to send messages to IMS; they are all queued at the same priority within IMS. I'm not aware of any priority system on the IMS message queue; even if it exists, the MQ-IMS Bridge does not take advantage of it.
I suspect your best approach to this would be to extend the "you will get your response later" period to allow the backlog to be processed before expecting the normal response period! Whether this is acceptable or not probably depends on how long the backlog takes to process.
