If you want to call this interactively, i.e. via M-x or a key-binding,
you will have to wrap this code in a defun with an interactive
from and thus turn it into a command. Like this:

#+BEGIN_SRC emacs-lisp
  (defun my-set-tag-in-region ()
    (interactive)
    (org-map-entries (function org-set-tags) nil 'region))
#+END_SRC
