The script returns OK / WARNING / CRITICAL errorcode according to what repquota (yes, it's Linux-only) returns (including gracetime, if active, excluding -for now- inode limits). These are obviously based on what you defined for the user/group via edquota:

If quota status is --, it returns OK.
If quota status is -+ or +-, it returns WARNING.
If quota status is ++, it returns CRITICAL.

plugin works fine.
for me missing the option for warning and critical :(
Owner's reply

Since the plugin is little more than a glorified repquota wrapper (ie. it works only on Linux as of now), it uses the repquota internals and returns the errorcode fitting the condition, that is returned by repquota.

To quote from the script:
$quota_status = "OK" if ($quota_status eq "--");
$quota_status = "WARNING" if ($quota_status eq "-+");
$quota_status = "WARNING" if ($quota_status eq "+-");
$quota_status = "CRITICAL" if ($quota_status eq "++");
