Hmm ... did not know that.

You are right. Org-mode *is* the major mode here.

Not an option :-( Muscle memory is too strong here :-)

Workable, as long as it is applicable for only the Org-mode. I am happy with
[S-tab] for all other Icicle operations.

Thanks !This option seems the best one right now. See code below for the 
solution I cam
up with. Quite possibly not the best lisp-code out there, but works ;-)

       (require 'icicles)
       (require 'icicles-menu)

       ;; Add a work around for the [S-tab] conflict between Org-Mode and
       ;; Icicles
       (add-hook 'icicle-mode-hook 'bind-my-icicle-keys)
       (defun bind-my-icicle-keys ()
         "Add the custom binding for [S-tab] when Icicles is used"
           (define-key icicle-mode-map [S-tab] 'bind-my-s-tab-for-org-mode))

       (defun bind-my-s-tab-for-org-mode (&optional arg)
         "Binds [S-tab] to cycle the outline in Org-Mode
and use the icicle mode functions otherwise."
         (interactive "P")
         (if (string= mode-name "Org")
             (org-shifttab arg)
       ;; End of the work around

       (icicle-mode 1)

Thanks a lot for the detailed post! This really helped me out.
