This is a little cheesy.  I asked offline, and found that it's because we store flags in the database as strings.  I'm not going to block on it, but we should keep an eye out for any other places where we need to do this with flags.  If this keeps happening, it means we're treating flags as objects (or at least key/value pairs), and we should switch to storing them in the DB as objects one way or another.
