If you are using a pool of MDBs to process the messages from the queue, then there is no guarantee each message is processed in the order they exist in the queue (unless you set the pool size to 1).
Also ordering is not guaranteed after failure. So if one of your MDBs fails, or the server goes down then the messages that had been delivered but not acknowledged yet will be cancelled and go back on the front of the queue, potentially changing the order. So relying on the position of a counter message seems risky to me.
