Yes I can.
But if the ListStore implements TreeSortable, I don't know why I need 
another TreeModelSort in top of the TreeModelFilter. Ie:
ListStore = Sorting properties
ListStore + TreeModelFilter = No Sorting properties, Filter properties
ListStore + TreeModelFilter + TreeModelSort = Sorting properties, Filter 
properties.
