I believe this clue is a double definition.
'mediocre' is the first definition.
(thesaurus)
'average' is the second definition.

(Other definitions for so-so that I've seen before include "Nothing to write home about" , "Tolerable, indifferent" , "Of middling quality" , "OK, but nothing special" , "Indifferently good" .)
(Other definitions for soso that I've seen before include "mediocre" , "Indifferent" .)
