What leads you to believe that the host you're scanning will send
packets back to your system (for you to determine whether or not ports
are open) if you're spoofing your IP?  Do you own the IP you're
spoofing?  

You have to get info back in order to know whether or not things are
open.  That's how scanning works.  More information about your network
setup might help us out a bit.
