Hi Nuno,

":noweb eval" means that noweb references are only expanded during
evaluation of the code, but not during export. This is why you get the
literal <<DEFVARS>> references in exported output. Here are the possible
values of :noweb and what they mean: https://orgmode.org/manual/noweb.html

Also note that if all of this is in the same file, both Script1 and Script2
will be tangled to the same file, you may want to specify different
filenames as the value of :tangle (see
https://orgmode.org/manual/tangle.html#tangle).

Hope this helps,
--Diego
