Bruce,
If you already have your answer please ignore.  Maybe this will help
someone else.  Or maybe someone can tell us an easier way to do this.

Here is what we ended up doing for something very similar.  We were
switching to a new ISP and only wanted one subnet to route to the new ISP
initially.

Our subnets are in the 10.x.x.x, 172.17.x.x, and 192.168.x.x range at
different sites.  The subnet we wanted to use the new ISP was the 10.1.14.x
subnet.

 ip access-list extended 101
  deny ip 10.1.14.0 0.0.0.255 10.0.0.0 0.255.255.255
  deny ip 10.1.14.0 0.0.0.255 172.17.0.0 0.0.255.255
  deny ip 10.1.14.0 0.0.0.255 192.168.0.0 0.0.255.255
  permit ip 10.191.14.0 0.0.0.255 any
  exit

 route-map policy NewISP permit 101
  match ip address 101
  set next-hop 10.1.7.250
  exit

 interface vlan.0.3014
  ip policy route-map NewISP
