ORDER BY is not pushed down in the following query:

SELECT J0.APPNAME, B.\"SYSID\", B.\"USERID\",
(select count from (select * from notes.RETRIEVE_NOTES where OBJECT_PKEY = B.USERID) as foo) as C_notesForObject
FROM \"SECURITY.BASEUSER\" as B left join security.sysinfo J0 on J0.sysid=B.sysid ORDER BY J0.APPNAME ASC

SECURITY comes from the DB2 translator
notes comes from a programmatic translator which does not support ORDER BY
