sortlist question

[Kevin Darcy]

Offhand, it seems like your sortlist should do what you want. But, to be
perfectly honest, although I have used sortlists quite extensively, I've
never used more than a single "sort" element (i.e. where each element
gets assigned a distance, etc.). Perhaps you could try simplifying the
sortlist and see where it breaks. At the very least, it may help you
diagnose the problem. You may even discover that a simpler sortlist
meets your requirements.
