Two more minor notes:
Your call to (interactive) should be (interactive "*"), to verify in advance that you're allowed to modify this buffer.
The use of (let ...) to note the location of the open-paren is unnecessary; that's what (save-excursion is for. Just drop out the bottom of the save-excursion, and you're back at that open-paren.
(defun sc-delete-delimiters-and-msg ()
"Deletes a pair of delimiters and the msg-expression attached in the
end (if one) leaving what' s inside intact. eg: [1,2,3].choose;->1,2,3"
