Probably because anything after quoted list is not evaluated.

This '((+ 2 2)) will not be evaluated to '(4)

To have `concat' evaluted you would need:

(list  (list "t" "Todo" 'entry
          '(file "~/02history/rcl.org")
          (concat "* TODO %^{Heading}\n  Brief: %^{Brief}\n"
                  "Detail: %?\n"
                  "Entered: %T\n  Link: %a\n") ))

As you see I would need to quote entry and list beginning with `file'
not to get such evaluated to make concat work.

And there is also no ensurance that program using customized variable
will take it as list to be evaluated. It is better you do with with
hand by using:

"* TODO %^{Heading}\n  Brief: %^{Brief}\n"Detail: %?\nEntered: %T\nLink: %a\n"
