The script names were at first assigned to help fontset.el which sets up
the default fontset by using script names in defining font specs (for
CHARSTE_REGISTRY of X fonts or "script" of OpenType fonts).  So there
was no precise semantics.

I think it is ok to change/fix char-script-table to improve some
behavior of Emacs without breaking fontset.el.
