As a workaround, you could simply list all movies, then list the reviews for that movie on the resulting page.

I've done something similar to that several times over the last few years, and it works well.

i updated my post to show what i am trying to do. it just seems really weird from a user standpoint not to be able to sort by the name. see http://scmapdb.com/reviews

I must be missing something here: in your scmapdb example you have the child page review in the review category and the parent page map in the map category. So why don't you just do a listpages with the category="map" and order="title"?

Edit: but of course there is a problem with the listpages module if you want more than one review of each map. In this case you could list all reviews for a map on that map's page.

I have a use case for this. I have a category called "calendar" that maps time onto a hierarchy of pages. I want to make specific events leaves at the bottom of the hierarchy. Then I want to use ListPages and tagging to make timelines and histories from those event leaf pages.

If ListPages order allowed me to sort by parent title, I could put the event pages in the "calendar" category. Instead, to accomplish what I want, I have to make a redundant category (called "events") containing a "timeframe" field, on which I can order my timelines.
