RFC3484: default address selection malfunctioning

Hi all,
      In Default address selction, From DNS query, the destination addresses are both a site local and a link scope addresses. the source addresses a site local address and a global address. So while pinging to the host(with name) according to RFC3484, the kernel should select the link local destination address and link local source address right? But linux kernel-3.0.26 is using the global address as source address and site local as destination address.

Why? is it a bug? And the DNS server address is a site local address. Had a default router with link local address

Thank you.
