Ok I'm happy with that answer.

Conversely if we want SRU to be used successfully with query languages other
than CQL, some of which might not support sorting,  we probably want SRU  to
have a sort parameter.

Note that the APD does list sort order as an abstract parameter.     I favor
adding a sort parameter to SRU 2.0.
