The quoting is incorrect. Variables are expanded every time a
command is run (except if it is the "AddTo..." or "+" command).
It seems you are running the ShadeWindowAndSort function in a
window context, for example with
Current ShadeWindowAndSort
Now, this processes the command "All ( ... echo $[w.width] ..."
Variables are expanded. Because a context window is currently
defined, $[w.width] and $[w.id] are expanded, and the values of
the *current* window are inserted.
Finally, the command "Piperead 'echo <current width> <current id> >> ...'"
is run, which is what you see. Note that the function does work
if it's run without a context window. In this case, the
$[w.width] is not expanded before the All command.
To make it short, replace "$[w.width] $[w.id]" with
"$$$[w.width] $$$[w.id]" and the function works fine.
