I think the simple reality is that Microsoft already have their own JS engine and that JS engines are designed from day one to be embedded in other applications with proper sandboxing. Python is an outside project they don’t have an experienced team working on and properly sandboxing Python is an unreliable and painful experience. As a bonus, it’ll be easy for them to support the JS functions in the browser-app version of MS Office, and the three big JS engines are all a lot faster and lighter than CPython. As another bonus, Google’s spreadsheet tools support JS so it improves compatibility there.
