That's for automating OpenMW-CS itself, e.g., bulk creating/editing objects. Many popular tools, such as Blender and GIMP, have Python automation, so it's quite logical actually.
Everything about development and the OpenMW source code.

There are a lot more data processing libraries out there for Python than Lua, and Python has a choice of well-tested, actively developed Qt bindings, including official ones. Sandboxing is less of a concern for the CS, and also native code is less problematic, too - if you want a native-backed Python library in your OpenMW-CS plugin, then just reference a pip package, and there'll be a native version for most platforms and a pure-Python fallback for the others.
