using priority support should do it, but there is no api that allows you to change the order of a pending message on a queue. You would have to consume and re send.
Using the jms api, find the message using a browse, consumer with selector matching the message id and issue a new message send. You could maybe build that logic with camel and have it kicked off with a specific event on an update queue. There are also jmx apis that wold allow u to find and remove a specific message.
