I can't get album sort to use originaldate (SOLVED)

The album sort doesn’t seem to respect originaldate no matter what I do and I’m not sure how to fix it. I set originaldate: yes in the config and added sort_album: albumartist+ year+ album+, but it keeps showing the albums release date without using originaldate.

I thought if you set originaldate: yes then it would convert the year tag to the originaldate year and thus fix the sort, but that’s not the case for me.

Here’s an example:

metaflac --show-all-tags ~/poolio/audio/music/Radiohead/Airbag\ _\ How\ Am\ I\ Driving_/01\ -\ Airbag.flac|grep -iE 'year|original'                                               
YEAR=2007
ORIGINALDATE=1998-04-21

When I list the albums, it’s showing this one as 2007, and not 1998 like I expect.

beet ls -a radiohead
Radiohead - 1992 - Drill EP
Radiohead - 1993 - Pop Is Dead
Radiohead - 1994 - Itch
Radiohead - 1995 - Fake Plastic Trees
Radiohead - 1995 - The Bends
Radiohead - 1997 - No Surprises / Running From Demons
Radiohead - 1997 - OK Computer
Radiohead - 2000 - Kid A
Radiohead - 2001 - Amnesiac
Radiohead - 2003 - Hail to the Thief
Radiohead - 2004 - Com Lag: 2plus2isfive
Radiohead - 2007 - Airbag / How Am I Driving?

Any ideas?

EDIT: I changed album_sort to this:
sort_album: albumartist+ original_year+

and fixed my issue.
