With the recent 9.1 patch Blizzard introduced its own scoring system. I expect it to replace the raider.io scoring system. Would be nice to have a filter for it if possible.

I pushed version 1.1.0-alpha which provides five new keywords to get the Blizz rating values. Feel free testing it and reporting back on me. Stable release should come next week.

Version 1.1.1 is now released.

Thank you for bringing this to my attention. I am currently a bit out of WoW, but will continue to support the addon and this sounds like a great extension if possible. Will look into this in a week as I am currently on holidays.
