Hmm, it could be that iso-left-tab is coming from your input method, so
#'x-keysym-on-keyboard-p doesn’t realise that the keyboard can generate it.

What is the output of the following code when you evaluate it in *scratch*?

  (describe-bindings-internal function-key-map)

If you make the binding unconditional--that is, if you change the code I
added to, for example--

  (when t ; (x-keysym-on-keyboard-p 'iso-left-tab device) 
    (define-key function-key-map 'iso-left-tab [(shift tab)]))

and rebuild, does it work?
