In your example, neither A or B is not executed.

Here is the problem. Script flag 3 is set for the environment of INVITE, 
local_route is executed, and being a top route, for a new SIP request 
(the MESSAGE sent by m_dump) the script flags are reset to 0. The 
condition for B is not met, when returning to 'route' scripts flags are 
0, so condition for A is not met as well.

In my example, if you set a flag in local_route, that flag will be set 
in 'route' after the call of m_dump.

Cheers,
Daniel
