Does setuid work on scrips? I know it did not in the past, but I
have not checked to see if that has changed.

No, it doesn't, and it never will. Making "root" a script's owner is not a "security issue".

I don't know if it ever did on Linux, but at one time you could have setuid and setgid on scripts. I've never investigated that since because it is a bad thing to do..
