[Plugin: Promotion Slider] order of slides

I’ve set up four “promotions” at this page (although all I really want is a slider):

But can’t get them to appear in the proper sequence. I’ve changed the publish date (and the modified date) but this has no effect.

Any advice?
Thanks.

PS if you go to the site and don’t see the slider it means that I’m trying another approach!
