Two tentative suggestions: 1. RosettaNet and ebXML (following RNet) provide a Notification of Failure over a different channel where the transaction end state might be ambiguous. 2. If (as in REST) the Order is a Web resource, one could always check its state. But I suspect this is a case for solutiong that are "good enough for what you are trying to do".
