Hi ColinM, thanks for your help, I found it very useful!!
The group user "editorial staff" had as main group "Public" and changing only its ranking did not sort the hope result.
I've try to increase the "Public" ranking over the Super User group, but this did not sort the hope result too.
So I've changed into Joomla -> Users -> Group the "editorial staff" main group to Registered, and this sort the hope result.
Then I've try to change, into JD, above and below the "editorial staff" ranking but this did not produce significant results.
