You are getting at the interaction between site-local addresses and
mobility. Can a mobile node have a site-local home address as well as a
global home address? If the implementation does not support mobility for
scoped addresses, then the destination address selection will need to be
modified.
How about a rule like this: if you are comparing two destination addresses
DA and DB, and Source(DA) is a home address and Source(DB) is not a home
address, then sort DA before DB.
In this example, DA would be a global address and Source(DA) would be a
global home address. DB would be a site-local address and Source(DB) would
be a site-local address, but not a home address.
