Get transformed meta_value output?

Hey guys!

My problem is I want to order posts with the meta_key “rating”, but the problem is the meta_value is a direct link to an IMDB movie (url) fetching the imdb rating and transform it into the imdb rating on output Is there a way around this, so it can sort by the transformed output and not the meta_value field that contains an URL?

I use the plugin “imdb-connector” to help fetch and transform the rating
