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.

Dang, another non-standard. According to this table the sort tag names for ID3v2.3 and ID3v2.4 used in foobar2000 are ALBUMARTISTSORTORDER, ALBUMSORTORDER, ARTISTSORTORDER and COMPOSERSORTORDER.   

as long as foobar writes eg TSOP into the ID3 tag for the artist sort name, what difference does it make what foobar chooses to call it?

However, the Kodi wiki tag table Music tagging (wiki) does need to be updated.  I believe Kodi is consistent with this: http://wiki.hydrogenaud.io/index.php?title=Tag_Mapping
