Template Css adding in my addon

[Asterix_ita]

I used this plugin to upload my template.css, but sometimes is it loaded and others no why? (vBulletin 4.1.5)

		
<plugin active="1" executionorder="5">
<title>CSS</title>
<hookname>parse_templates</hookname>
<phpcode><![CDATA[
			if($vbulletin->options['ct_list_active'])
				{
					$template_hook['custom_css_list'] .= ',ct_thread.css';
				}
]]></phpcode>
</plugin>

Is there any other way to load your css template?

In several articles I found this code, but everyone says outdated

		<plugin active="1" executionorder="5">
			<title>CSS - Inject CSS into vBulletin</title>
			<hookname>css_start</hookname>
			<phpcode><![CDATA[if(in_array('vbulletin.css',$matches[1]))
{
   $matches[1][] = 'ct_thread.css';
}]]></phpcode>
		</plugin>

Thanks

Regards
