Joe, Many people asked the same. so I am cc'ing the
group.
my topo:

R1-----Mpls cloud--------R2----VPN prefixes/nets

R1, R2 = PE's
R1 = igress, R2 =egress in this example
R5 is in the cloud, is the RR

goal:
from R1, traffic to prefixes with RT = 1:2 shd take
tunnel101. traffic to prefixes with RT = 1:3 shd take
tunnel102. 

R2 config:

router bgp 1
 neighbor 10.10.10.5 remote-as 1

 address-family vpnv4
 neighbor 10.10.10.5 activate
 neighbor 10.10.10.5 route-map foo out
!
route-map foo permit 10
 match extcommunity 99
 set ip next-hop 10.10.10.101
!
route-map foo permit 20
 match extcommunity 98
 set ip next-hop 10.10.10.102
!
route-map foo permit 30
!
ip extcommunity-list 98 permit rt 1:3
ip extcommunity-list 99 permit rt 1:2
!

Config on R1:

interface Tunnel101
 ip unnumbered Loopback0
 tunnel destination 10.10.10.2
 tunnel mode mpls traffic-eng
 tunnel mpls traffic-eng path-option 10 dynamic
!
interface Tunnel102
 ip unnumbered Loopback0
 tunnel destination 10.10.10.2
 tunnel mode mpls traffic-eng
 tunnel mpls traffic-eng path-option 10 dynamic
!
ip route 10.10.10.101 255.255.255.255 Tunnel101
ip route 10.10.10.102 255.255.255.255 Tunnel102
!
