I don't see how scores affect that. Suppose I have two trees and a
rename-cache file:

$ git ls-tree -r HEAD^
100644 blob d00491    path1/foo
100644 blob d00491    path2/bar
$ git ls-tree -r HEAD
100644 blob 0cfbf0    path1/fooo
100644 blob 00750e    path2/barr
$ cat rename-cache
d00491 0cfbf0 <score 1>
d00491 00750e <score 2>

How can I be sure "git diff HEAD^!" will rename path1/foo =>
path1/fooo and path2/bar => path2/barr, not path1/foo => path2/barr
and path2/bar => path1/fooo?
