I am already fixing things to release Falcon with dual license GPLv3
and FPLL.

Ok, I get the point. I actually wanted to protect scripts but the only
fact that they are mentioned may lead to think (also, may bring out
the legal question), that scripts were mine in the beginning and I am
so kind to set them free. I will remove the script things, and just
require that closed source works using FPLL state it.

Pitifully, this isn't the case, but I see that using the term
"scripts" is a near-miss to my target here. As I said, "scripts" will
be off.
As it is now, it is unclear if you can take your scripts, run them
with an interpreter you did and release your scripts and your
interpreter without FPLL, and that wasn't my aim. Removing the term
script and bounding FPLL to the product to which is applied (in this
case, Falcon engine), seems much more reasonable.
Thanks for clarification.
Giancarlo.
