publishing <lisp> tag in planner task

Hi all,

I am using the <lisp> tag to insert some automatically computed stuff 
in a page. Works fine, even for publishing.

However, in case the <lisp> tag is part of a planner task description, 
then the result of the call is printed in the planner page, but the 
published page shows the actual lisp code. Is the intended behaviour? 
How could I get the results printed in the published output?

BTW: Perhaps I could use the [[lisp:/(my-function-call)]] instead? So 
far, I was not able to let this construct show the result of 
(my-function-call) in the page.

Thank you!

Best,
Torsten
