I think your problem comes because of releases with file tracks.
Pone's script (artist+album) gives the correct result.
I suggest you use Pone's script with default settings (backup your settings first, copy mp3 file provided from Pone's script, it should be placed somewhere in folder %appdata%/mp3tag).
Mp3tag Discogs script, searches by album title only (more precisely the release title). If you search with combined fields (e.g. artist albumtitle) you won't get any results.
If you search with 'Around The World' you still won't see your release (Arty) because it is not in the first page of the results. There are 37 pages with such albums.
Mp3tag does not yet offer a way to support multiple pages. You have to know the parameter and pass it to the script search text (e.g. &page=2).
