Related Posts using Tag

Hi,
Is there a way to update this plug-in to use a specific tag for Related Posts? For some reason, it is only pulling related posts on the same category with the same tag.. but I want it to show all related posts with same tag everywhere. does it make sense?

Here is what I am working on.
This is the actual result..
http://www.deepvision.no/deep-vision-featured-in-the-news

but these are the posts (excluding the post currently active) that should show up.
