As long as your plugin complies with the Screen Output and Plugin Return
Codes (at the minimum) of
http://nagiosplug.sourceforge.net/developer-guidelines.html#AEN73,
check-by-ssh should pass the appropriate information back.

Can you run your command directly from ssh? i.e. ssh user at hostname
"cscript //nologo c:\nrpe_nt\check_cpu.vbs -H testserver -w 80 -c 90"
