Well, if you need to just preserve the order of received (event) tuples then why not use trident instead? Trident ensures correct ordering (chronologically) as well as exactly once processing without any gimmicks; sorting it secondary to the event generation sounds like you will enter into quite a bit of hassle for no reason.
