Perhaps ob-ruby.el is to blame.

#+begin_src ruby
  2 + 2
#+end_src

The above snippet calls org-babel-script-escape twice: first with "4"
and then with 4.  The first one happens with the org-babel-ruby-evaluate
call (which leads to an org-babel-ruby-table-or-string call) in
org-babel-execute:ruby and the second happens with the direct call to
org-babel-ruby-table-or-string in org-babel-execute:ruby.

Is the results-params check and call to org-babel-ruby-table-or-string
in org-babel-ruby-evaluate needed?  It seems like org-babel-execute
already covers this processing.
