Correct, the new Blastacular Pack is required in order to enter some of the playlists as of the most recent update.
If you have the Blastacular Pack and still get this error, most likely you need to re-download the maps. That's because Bungie has corrected a few exploits in Tombstone and only the new version is valid for matchmaking.
