Ups, while I was writing my extended solution yours sit here for more
than an hour already ...

Well, I post mine anyway, it has one additional feature - it stores all
Org commands with their keybindings, if they have one, as an alist in a
global variable:

#+begin_src emacs-lisp
  ;; usage examples:
  (setq omm-org-cmds-with-key-bindings nil)
  
  (defun omm-get-org-cmd-syms-with-key-bindings (s)
    "Store a list of symbols/keys pairs in obarray that are Org commands."
    (and (commandp s)
         (string-match "\\(^org-\\|^orgtbl-\\)" (symbol-name s))
         (with-temp-buffer
           (org-mode)
           (let ((cmd-key (substitute-command-keys
                           (concat "\\[" (symbol-name s) "]"))))
             (push
              (cons s
                    (if (string-match "^M-x " cmd-key) nil cmd-key))
              omm-org-cmds-with-key-bindings)))))
  
  (mapatoms 'omm-get-org-cmd-syms-with-key-bindings) 
  
  (nth 20 omm-org-cmds-with-key-bindings)
#+end_src

#+results:
: (org-clock-in . C-c C-x TAB)
