Ah, now the problem appears. It says "No such language mode:
mathematica-mode".
So there is a mismatch between the name mathematica (which I used as name
in org-babel extension) and the name mma-mode (which is provided by
mma.el).
However, as auto-mode-alist suggests (where there is ("\\.m\\'" .
mma-mode), and no entry with mathematica-mode), I still have no idea
why org-edit-special looks for mathematica-mode instead of mma-mode.
