Maybe you intended to have the HERE document being interpreted by the shell, but this doesn't work either, because passing a multi-line string to qx does not cause the shell to execute a multi-line script.
Couldn't bother to try? 
$ export PS2=""; perl -E '$x = `cat <<FOO
hello
world
FOO`; print uc $x'
HELLO
WORLD
$

qx doesn't filter out newlines, and the shell is smart enough to know how to deal with newlines.
