I can't follow your problem, the script submit_check_result_via_nsca expect
the returncode as an integer and forwards that to the nagios daemon. I don't
know any location where strings are accepted. If I submit a passive
checkresult to the script like: 
 submit_check_result_via_nsca localhost SSH 2 "CRIT: foo bar baz"
Everything goes as expected:
 nsca[19632]: SERVICE CHECK -> Host Name: 'localhost', Service Description:
 'SSH', Return Code: '2', Output: 'CRIT: foo bar baz'
which results to: 
[1293958612] PASSIVE SERVICE CHECK: localhost;SSH;2;CRIT: foo bar baz
[1293958612] SERVICE ALERT: localhost;SSH;CRITICAL;SOFT;1;CRIT: foo bar baz

So unfortunatly I can't see your problem.
