This is one of those things that is, IMO, strictly a "feel good" thing that's sometimes insisted upon by the product manager and all the information in the world about "this is really meaningless" falls on deaf ears.
If you simply have no choice (a position I've been because it wasn't worth the argument), you can do the star thing. That is, display 5 stars for percentages between 80-100, 4 stars for 60-80 etc. and not display the percentages or raw scores at all. But as others have said, it really isn't providing any additional information, and IMO misleading the user...
