It is not clear to me what you want here. Do you simply want a
function that deletes the number at point and inserts number + X into
the buffer again? What do you want to achieve?

If you simply want a skeleton for lists, you could use something like
this:

(defun wy-list-skel ()
  (interactive)
  (let ((num 0))
    (skeleton-insert
     '(nil
       ("Type something: " 
        (number-to-string (setq num (1+ num)))
        ". " str "\n")))))

Hexadezimal:

(defun wy-hex-list-skel ()
  (interactive)
  (let ((num 0))
    (skeleton-insert
     '(nil
       ("Type something: " 
        (format "0x%02x" (setq num (1+ num)))
        ". " str "\n")))))
