Ok, finally sorted it out. Babel doesn't load ox-* files by itself (except for ob-haskell & ob-latex). But, in my case, the code block's result is a table. In consequence Org needs org-table which in turn requires some ox- files and THEN org.el evaluates (after ox.el) 'org-export-backends'. Thank you for your patience. Now I can sleep soundly.
