Draft says:

   Rule 4: Prefer home addresses. 
   If SA is simultaneously a home address and care-of address and SB is 
   not, then prefer SA. Similarly, if SB is simultaneously a home 
   address and care-of address and SA is not, then prefer SB. 
   If SA is just a home address and SB is just a care-of address, then 
   prefer SA. Similarly, if SB is just a home address and SA is just a 
   care-of address, then prefer SB. 
   An implementation may support a per-connection configuration 
   mechanism (for example, a socket option) to reverse the sense of 
   this preference and prefer care-of addresses over home addresses.

If the addresses are the same at the view of the rule 
1: Prefer same address, 2: Prefer appropriate scope, 3: Avoid deprecated
address, 4: Prefer home addresses, address on interface B will be used.

Please tell us further details (kernel version, source address candidates,
destination and so on) if you think the behavior is buggy.
