Giac works for me as well (I did 2+2).

I searched in the code (looking for one of the Giac menu items using 
ack, so that I would find where it is defined) and I _think_ I figured 
out a part of the answer: you have to look inside the ...-menus.scm 
Scheme file inside the progs subdirectory of the plugin.

Some of the plugins there use a  (if (not-in-session?) ...) clause where 
in the true branch they evaluate a (link scripts-eval-menu) form. I did 
not understand where the scripts-eval-menu is defined; the name has 
"scripts" inside, so maybe it does _that_; and Python does not have it.

I don't know and I am not able to figure it out in a short time, sorry. 
Perhaps one of the developers is listening and can tell you more.

TeXmacs is opaque sometimes; I am thinking of starting a Wikibook but if 
ever I do it, it will take time.
