Match on regex should work, something like

if (&Cisco-AVPair =~ /ip:route=([^ ]+) /) {
  update reply {
    Framed-Route := "%{1}/28"
  }
}

if the netmasks aren't all the same you'll need to change that as well
of course - I don't think there's anything to convert the netmask into
the number of bits, but a switch statement should do it easily for the
limited number of cases.
