After some thinking, my conclusion is that we should import the ISO 15924 database from https://unicode.org/iso15924/, use a script similar to admin/unidata/blocks.awk to generate an alist from it that maps Emacs script names to ISO 15924 tags, and then access that alist from uni_script to get the correct script information to Harfbuzz. Patches implementing that are welcome.
