Can I include review scores in CV?

What is OK and what is wise may not be the same thing. I doubt that this would be wise. Instead, I'd list it as "in preparation" if you intend to revise and submit elsewhere. Showing work in progress is a good thing and forward looking. Being rejected is less of a good thing, and also backward looking.

Scores alone without the associated reviews have only little informative value, since the final decision usually does not depend on a threshold, but on a discussion between PC members. Maybe the reviewers who gave a positive score were "informed outsiders", whereas the most expert reviewer saw a major flaw and fought against the paper's acceptance? From just looking at the scores, we can't know. Therefore, I would be skeptical if I was reading your CV and saw this entry.
