Thanks Nick!
I downloaded StartOzServer.oz into a suited directory.  The file ob-oz.el had 
to be adapted  for looking for StartOzServer.oz in that directory. 
Now executing (C-C C-C) on a code block the process Org-babel-OPI-socket is 
started but now I get the error message:

Org-babel: executing Oz expression
Create OPI socket for evaluating expressions
open-network-stream: make client process failed: Connection refused, :name, 
*Org-babel-OPI-socket*, :buffer, nil, :host, localhost, :service, 6001, 
:nowait, nil

If I execute (C-C C-C) once more I get a different message:

executing Oz code block...
Org-babel: executing Oz expression
Create OPI socket for evaluating expressions
org-babel-insert-result: Wrong type argument: markerp, nil

If I do it a third time then all works fine, i. e. executing the code block

#+begin_src oz :results value
39 + 3
#+end_src

results in insertion of
#+RESULTS:
: 42
into the org file.

It seems a bit strange for me, but it is usable.

[this "answer" is uncontaminated by such mundane things as testing - I know
 nothing about Oz except what I read in contrib/lisp/ob-oz.el and I don't have
 Mozart installed on my machine (except for various pieces in my Music folder)]

You need to start the server using the contrib/scripts/StartOzServer.oz
script.
