you can take advantage of the second, optional argument to split() and
save the call to substitute():

:call setline(line('.'),join(sort(split(getline('.'), ',\s*')), ', '))

This splits the line on every comma optionally followed by white-space.
If there is a trailing comma, split() automatically removes it. Like in
your second version the comma has to be added back later.
