Plugin for Postbit no longer works in 3.7.4

[wottech]

I wrote a plugin for a garage module to provide a link from the postbit back to the user's garage. It works fine in 3.7.3, but does not work in 3.7.4. Was there a change in template conditional or something in 3.7.4 that would cause it not to work? See the plugin code as well as the template code below..

if(THIS_SCRIPT == 'showpost' OR THIS_SCRIPT == 'showthread')
{
   switch ($vbulletin->options['postbittype'])
    {
      case 1: $pbq = "ORDER BY `main_vehicle` DESC LIMIT 1"; break;
      case 2: $pbq = "ORDER BY `main_vehicle` DESC LIMIT 1"; break;
      case 3: $pbq = "ORDER BY `vehicle_id` DESC LIMIT 10"; break;
    }  
	$sql = $this->registry->db->query("select *, " . TABLE_PREFIX . "garage_user_vehicle.user_id AS PostUser 
    	from " . TABLE_PREFIX . "garage_user_vehicle  
	LEFT JOIN " .TABLE_PREFIX . "garage_makes
  	on (" .TABLE_PREFIX . "garage_user_vehicle.make_id=" .TABLE_PREFIX . "garage_makes.id)
  	LEFT JOIN " .TABLE_PREFIX . "garage_models
  	on (" .TABLE_PREFIX . "garage_user_vehicle.model_id=" .TABLE_PREFIX . "garage_models.id)
	WHERE " . TABLE_PREFIX . "garage_user_vehicle.user_id='" . $post['userid'] ."' " . $pbq);

    if($this->registry->db->num_rows($sql) > 0) 
    { 
	if($vbulletin->options['postbittype'] >= 3)
	{
		while ($entry = $this->registry->db->fetch_array($sql))
		{
			$newyr = substr($entry[made_year], -2);
			eval('$template_hook[\'postbit_userinfo_right_after_posts\'] .= "' . fetch_template('postbit_garagelink') . '";');
		}
	} else {
		$entry = $this->registry->db->fetch_array($sql);
		$newyr = substr($entry[made_year], -2);
		eval('$template_hook[\'postbit_userinfo_right_after_posts\'] .= "' . fetch_template('postbit_garagelink') . '";');
	}
    }
}

<if condition="$vbulletin->options['postbittype'] == 1">
<div><a href="garage.php?do=user_garage_view&id=$entry[PostUser]">'$newyr $entry[make] $entry[model]</a></div>
</if>
<if condition="$vbulletin->options['postbittype'] == 2">
<div><img src="images/garage/car.png"><a href="garage.php?do=user_garage_view&id=$entry[PostUser]"> $post[username]'s Garage</a></div>
</if>
<if condition="$vbulletin->options['postbittype'] == 3">
<div><a href="garage_vehicle.php?do=view_vehicle&id=$entry[vehicle_id]">'$newyr $entry[make] $entry[model]</a></div>
</if>
<br />

The postbit type value is set from the ACP. Thanks for any insight into this!
