MySQL: Sort GROUP_CONCAT values

by

In short: Is there any way to sort the values in a GROUP_CONCAT statement?

Query:

GROUP_CONCAT((SELECT GROUP_CONCAT(parent.name SEPARATOR " » ") 
FROM test_competence AS node, test_competence AS parent 
WHERE node.lft BETWEEN parent.lft AND parent.rgt 
  AND node.id = l.competence 
  AND parent.id != 1 
ORDER BY parent.lft) SEPARATOR "<br />\n") AS competences

I get this row:

Crafts » Joinery

Administration » Organization

I want it like this:

Administration » Organization

Crafts » Joinery
