My question: Is there a better way to tag the episodes so that way they are sorted by something other than the MP3 Title tag?

Not at the moment, they're only sorted by title in the current release. Podcast support was added fairly recently in the scheme of things so we're still making improvements and figuring things out. We could update the firmware to use the year tag to sort podcasts views, as that seems to match where the "release date" info seems to be set (at least with gPodder, though it'd be great to confirm that other podcast downloaders do it this way too). I've opened an issue for this on codeberg here.

I tried setting the MP3 Track Number tag to sort episodes, but this did not seem to translate to the Tangara.

At the moment they're only sorted by title and not album/track order, but that wouldn't be a difficult change either. Other indexes are sorted that way so we do have support for it, but it's not used at the moment for podcasts. But I think it's probably best to use the "year" tag first (often for podcasts this is a date, not just a year), since that's what seems to be the convention.
