Actually, MakeMaker can do just fine installing a set of scripts. Tom Christiansen's pmtools package is such a set, so you could look at the Makefile for that and see how it's done.

Essentially, you just use EXE_FILES:

    WriteMakefile(
        'NAME'         => 'Foo',
        'EXE_FILES'    => ['foo', 'bar'],
    );
