If you don't use it interactively (`M-x customize-variable')
then you are on your own wrt such type checks.  IOW, if you
are using Lisp instead of setting it interactively, then check
first, before setting.  Use (get 'tab-width 'custom-type).

That raises an error only because you didn't quote `org-tags-column'.
If org.el is loaded then the error is a wrong-type-arg error.
If it is not loaded then the error is an undefined-variable error.
