Can you specify exact commands you are issuing to add/remove routes?
(or "route monitor" output if you are doing this from some dynamic 
routing software)

The following order works for me (8.2-STABLE):

16:44 [0] bibi# route add -net 54.10.208.162/30 10.11.0.1
add net 54.10.208.162: gateway 10.11.0.1
16:45 [0] bibi# route add -net 54.10.223.236/20 10.11.0.1
add net 54.10.223.236: gateway 10.11.0.1
16:46 [0] bibi# route add -net 54.10.208.130/30 10.11.0.1
add net 54.10.208.130: gateway 10.11.0.1

16:46 [0] bibi# netstat -rn -finet | grep 54
54.10.208.0/20     10.11.0.1          UGS         0        0    em0
54.10.208.128/30   10.11.0.1          UGS         0        0    em0
54.10.208.160/30   10.11.0.1          UGS         0        0    em0
16:46 [0] bibi# route delete 54.10.208.0/20
delete net 54.10.208.0
16:48 [0] bibi# route delete 54.10.208.128/30
delete net 54.10.208.128
16:49 [0] bibi# route delete 54.10.208.160/30
delete net 54.10.208.160
16:49 [0] bibi# netstat -rn -finet | grep 54
16:49 [0] bibi#
