Sorting Games by Original_Release_Date always returns null first

I am trying to get a list of "new games" for my app. I was hoping to sort games by original_release_date descending, but no matter how I sort, the games return with a null release date.

Example requests:

http://www.giantbomb.com/api/games/?format=json&api_key=[key]&limit=10&field_list=id,name,original_release_date&sort=original_release_date:asc

http://www.giantbomb.com/api/games/?format=json&api_key=[key]&limit=10&field_list=id,name,original_release_date&sort=original_release_date:desc

I feel your pain, I'm also having trouble with this.

Ditto

Same here, any solutions?

Bump. All I ever get, whichever way anything sorts, in games or releases, using any date field, is nulls.
