1) There is no "albumartisssort" (note 3 x "s") tag. Kodi parses the ALBUMARTISTSORT (TSO2), ARTISTSORT (TSOP) and COMPOSERSORT (TSOC) tags to find sort names for the artists given in the tags. It is obviously possible to confuse this parsing, but it will handle the obvious.
2) It always reads the ALBUMARTISTS tag, if it is present, in ID3, APE (Mp3 files), Vorbis (FLAC files) tag formats and mp4 files. However it only uses these values if there are multiple artists - that was the purpose of this tag: to clarify/separate out multiple artists from a single description string. So you are correct, if there is only one artist to match to an mbid then Kodi uses ALBUMARTIST, not ALBUMARTISTS
The parsing logic is in code here https://github.com/xbmc/xbmc/blob/Krypto...um.cpp#L46
3) For mp4 files Kodi is looking for the ALBUMARTISTS tag to be called "----:com.apple.iTunes:ALBUMARTISTS" (similar to "----:com.apple.iTunes:ARTISTS" for ARTISTS) , but I don't know if it made it into the full release of Picard. Neither are documented, so probably best asking them.
