Practically speaking, -0.001 is equivalent to zero. The difference is that if 
you use zero, the SPF tests may be skipped alltogether (usualy when a test 
score is zero, SA bypasses performing it), and if it is -0.001 the test will 
be performed and its result may be reflected into SA added mail headers 
(depending upon configuration).

So -0.001 doesn't change anything for the actual scoring of the message except 
that it allows having the SPF results added to the message headers.
