I was not aware of any implied hierarchy with tags. The order is not
important as far as I know, and what you describe as mix-and-match seems
ok. There is an idea of inheritance, e.g. sub-headings can inherit tags
from higher headings.

In any case, you should be able to use agenda queries to find headings that
are lisp and not emacs, lisp+orgmode, etc.

I am not sure about the org-mode tag. In the past, emacs splits that into
:org:mode: for me.

What do you want to do with the tags?
