This is an e-mail from the MapRaider staff:
Thank you! We've updated the site with those you listed and also included swapped out "Deathmatch" for "Free For All" mode listed on the official OpenArena About page just for consistency.
Now I just need someone to help me get some OA maps added before Mapraider v2.0 rolls out
So, if someone is interested, we're waiting for you!!! ^^
