Works perfectly with vB 4.0.x with a minor modification in the first code block,

	/**
	* Handles a [ high ] tag. Displays a preformatted string.
	*
	* @param	string	The code to display
	*
	* @return	string	HTML representation of the tag.
	*/
	function handle_bbcode_high($code , $option)
	{
		global $vbulletin, $vbphrase, $stylevar, $show;

		// remove unnecessary line breaks and escaped quotes
		$code = str_replace(array('<br>', '<br />'), array('', ''), $code);

		$code = $this->strip_front_back_whitespace($code, 1);

		if ($this->printable)
		{
			$code = $this->emulate_pre_tag($code);
			$template = 'bbcode_high_printable';
		}
		else
		{
			$blockheight = $this->fetch_block_height($code);
			$template = 'bbcode_high';
		}

	//	eval('$html = "' . fetch_template($template) . '";');
	//	return $html;

		$templater = vB_Template::create($template);
			$templater->register('blockheight', $blockheight);
			$templater->register('code', $code);
			$templater->register('option', $option);
		return $templater->render();
	}
