This is not about sorting but about checking if there are elements at all.
And the information if an area has got elements is available via pages only.
In tt_content you can just find a value for "pid" to make sure the element
is related to a particular page.
But this doesn't necessarily mean that it is used in any area, since it
might be a "non used element".
