It depends on how low-level/from-scratch your scripts are going to be. Ruby would be useful as its used by other config management tools, if that's something you need, but for command-line-tool scripts, Golang would be very useful. I'm currently converting some Python scripts into Go so that they're smaller and don't have prerequisites (e.g., version X of Python).
