Look in the API (link in Quick Links) for the function "standard_error" and you should see how to modify the message. Then just put a condition around each error based on the usergroup:

PHP Code:

if (is_member_of($vbulletin->userinfo, x,y))  {
error 1
} else if (is_member_of($vbulletin->userinfo, a,b))   {
error 2
} else {
error 3
}
