well, assuming I understand your setup and how your are thinking about 
it, you are wrong about this.  Ignoring shared groups (backgrounds), 
the message path  from a button, say, for a mouseUp, goes like this:

front scripts
button clicked
groups the button is in, if any
card the button is on
stack the card is in
*
its main stack if it is a sub stack
libraries
back scripts

(* There is a bug.  In the standalone, the libraries seem to be also 
here.)

Frontmost does not enter into this.

Look at 'send', 'call' and 'value()'.
