If you look at that section of the code in mod_rewrite, you'll see
that mod_rewrite makes that variable available to its
variable-expansion mechanism, but doesn't actually set it in the
environment.  Hence it is only available for mod_rewrite.

You may be able to force it into the environment, using something like

RewriteCond %{REQUEST_FILENAME} (.*)
RewriteRule .* - [E=3DREQUEST_FILENAME:%1]
