The Makefile copies everything into the .../tex/... tree, that causes the problem.
It would be fixed by aligning the directory structures of CTAN and the Makefile were aligned.
More generally, have you thought about modifying the search order so that the home tree is always searched before the system tree regardless of the subdirectory?

In my case "make install" installs the Lua file in .../tex/..., not in /scripts/. Furthermore, the Lua file is not intended to be executed (e.g. it has no intepreter line), but is installed with executable permissions by TeX Live. I think I'd prefer having it in /tex/ (like luaotfload.lua, fontspec.lua), and it should not be executable.
