Public response also:

#1 I tested it during one pen-test case in December 2015. Exact
version was 3.2.1. I haven't set up this environment myself.

At the moment I used "Google Hacking" to find some dotCMS.
Use search phrase inurl:/html/portal/login.jsp

From login page you can see, what is the current version on this site,
change path to /categoriesServlet and you probably can see the output
like I described in my blog post. I saw described output from
different versions, like 2.5.4, 3.2.1, 3.5, 3.6.

From one site I also got an error - so, maybe there are some other
pre-conditions which I don't know. If you can figure it out, share it
with others also.

#2 You can not use UNION after ORDER BY statement, this is the way how
SQL works. And if you have vulnerability in order by or sort
parameter, then your entrypoint is after ORDER BY statement
