Hi Luis,
below my approach.
Several comments in code, file and png attached.
Hope there are no problems, I tested it with 2.16.2 up to 2.17.16 from latest master.
\version "2.16.2" %% and higher
%% Although, it is public I didn't manage to get full acces to
%% `default-script-alist´ from/scm/script.scm.
%% It is possible to modify the values, though, I couldn't create a new entry.
%%
%% Anyway, working on a copy of `default-script-alist´ guarantees no bleed-over.
#(define my-script-alist default-script-alist)
%% Some crazy stencils :)

%% A macro setting the lists from above in the copy of `default-script-alist´
