[Plugin: Customizable Post Listing]

I am trying to use the Customizable Post Listing plugin on my ‘tagged posts’ page, to sort/reorder the posts based on the latest comment rather than by date (which is the default). Using the code examples included with the plugin and using the tag $orderby = 'max_comment_date' I am able to order the posts that way, but it includes all the posts on the site. I see the plugin works with categories, but I don’t see any options for tagged posts.

For example, on the page example.com/tag/blue I would like order all the ‘blue’ posts with latest commented post at the top, and to have example.com/tag/red ordered the same with the ‘red’ posts. Now it just shows all the site’s posts, regardless of which tagged posts you are trying to display. Any ideas on how I can include the tags when ordering posts? Thanks in advance.
