Ordering children by their parents

[Tyssen]

I have a series of products which are attached to 'collections' which are their parent pages. I need to be able to output the products by their parents order. At the moment I have this: 

$products = $pages->find("template=product,stock=1");

which worked fine when I first created the site because all the products were entered in the correct order, but now a new collection has been added that needs to go first. (Parent pages have a different template than the individual products.)

I've tried adding sort=sort but as mentioned in the docs it doesn't really produce the desired result.

So how would I go about it?

I think you can do this

$products = $pages->find("template=product, stock=1, sort=parent, sort=title");

Actually what I needed is sort=parent,sort=sort but thanks for pointing me in the right direction. I didn't see any mention of anything like that in the docs or in searching the forum.
