Cool stuff!

(used to be pretty good at CSS et al :-): I'm pretty sure that what you 
describe doesn't exist.  

I wrote something similar a year or two ago, for IE only (pre-stable 
Mozilla), ugly and hackish internally, but I think UI-wise it worked 
well.  FWIW, I would suggest eliminating the separators and comparing 
the overlap between the moved box and the nearest other boxes to 
determine the new order.  This worked pretty well as an intuitive 
experience.  I was building a tree of boxes with my UI, rather than a 
column, so the logic got a bit hairy in places, but for a column this 
shouldn't be that bad...
