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".  In other words, buying books
requires less certainty than big funds transfers.
