script files are hard to reproduce in systems with different locales

I noticed the .sh and .csh files provided in the repo are different from what I get from trying to use the makefile myself. After some digging, I found it's because github action's locales are different from my system's, which cause sort to show different output.

So I suggest adding something like export LC_ALL=C to the makefile to force sort to use the same locale regardless of which system it is run.

Good idea. I'll look at this when I get a chance. In the mean time, PRs are very welcome :)
