I understand your problem but I am having trouble trying to think of a reliable solution.

The 3G link. Should that really be "up" when it is not required? Would that then be consuming the allowance? Perhaps other members, who have a failover backup link for their own situation, will be able to advise in general terms.  :-\

Do you have a public IP address on the 3G link? Arn't most behind CGNat?

I'm not sure how Firebrick work the 3G failover.
On 2 routers I own that have 3G failover the 3G link is completely down until required.
It would not respond to any ICMP pings until activated.

Are you able to tell if the 3G failover is connected when the DSL lines are up?

Did the 3G IP address respond to ping during your failover testing?   I always prefer a fail over path to be live at all times, so you know it's ready for when it's needed, however I wonder whether your dongle only brings up the link when there's outbound traffic.
