Assuming those users with less than x posts are in a different usergroup, just add something at the beginning, such as:

PHP Code:

if ((!isset($vbulletin->userinfo['userid']) OR $vbulletin->userinfo['userid'] == 0) OR is_member_of($vbulletin->userinfo, x, y, z))
{
// if you aren't logged in or a member of groupid x, y, z, you get no permission
        print_no_permission(); 
}
