I was about to open a ticket based on this issue on my own site, but I notice it on the demo too.

If I go to listings, and click the dropdown Sort By: and choose price ascending for example, the featured listings show:
$4,500
$30,000
$350,000
$249,000
$2,500,000
$299,000

So they're not being sorted by price ascending within the featured listings which appear above the standard listings...
