At least on my machine, this specification is illegal: it generates an entry in org-key-map, but the key presses yield an "undefined" message. Binding the command to (kbd "C-c C-<tab>") instead works, but not on a tty. It's been my understanding that "TAB" is the ascii control character, identical to C-i, and hence "C-TAB" cannot work. "<tab>" is the GUI system's key event (in my case, X), and does not work on a terminal.
