Have many long lines like the following:

(AA 10, (xxx-xx-xxx) BB, 200 A)
(Test 20, (YYY-YY-YYY) DCB, 100000 BBB)
....

How to add a comma to the positions which do not have?
Expected output is
(AA, 10, (xxx-xx-xxx), BB, 200, A)
(Test, 20, (YYY-YY-YYY), DCB, 100000, BBB)
...

Preferred awk/sed, but perl is OK too.
Thanks in advance.
