Per https://github.com/ofiwg/libfabric/issues/1217#issuecomment-131264316, you really need to specify FI_ORDER_SAS for both transmit and receive if you want to guarantee ordering on FI_EP_RDM endpoints (and you do; the MPI-style tagging interface doesn't make much sense unless the underlying fabric provider guarnatees ordering).
