I'm a bit confused about a failover and was hoping to clear up some questions..

I've got Router B (Routing protocol is RIP) with two serial interfaces
Serial 0/0 - T1
Serial 0/1 - Frame

My routing setup on Router B is:
ip route 0.0.0.0 0.0.0.0 <T1 next-hop IP>
ip route 0.0.0.0 0.0.0.0 <Frame next-hop IP> 125

Now, on Router A (also using RIP), I've got a route-map that routes traffic from LAN of Router A (source) with a destination of LAN on Router B over the T1 line.  
Route-map X permit 10
Match address 112
Match interface (T1 interface)
Set ip next-hop (T1 next-hop)

I pulled the T1 line from CSU/DSU from Router B and we lost connectivity with Router A's LAN.  If that because Router A is forced to route traffic over the T1 due to my route-map policy?  Why did the traffic not begin routing over the frame?
