Sort by parent, then by title

[caribou]

Hello! I'd like to sort search results by title within their parents' parent. This sorts by title alone:

foreach($pages->find("template=individual")->sort(title) as $individual) {

echo "<option value='".$individual->name."'>[".$individual->parent->parent->title."] ".$individual->title."</option>\n";    

}

And gives me something like

<option value="Bob">[Grandpa Joe] Bob</option>

I'd like to list all grandchildren of Grandpa Joe in order, then all grandchildren of Grandpa Lou, etc, grouped by grandparent name. What's the best way to do that?

I guess this will work:

$pages->find("template=individual, sort=parent.title, sort=title");

$pages->find("template=individual, sort=parent, sort=title");

Thanks very much, this worked! In this case, rootParent worked too.
