The above looks like old-style, "canonical six" trivial ACL.  Now,
cp(1) shouldn't even try to copy the ACL in this case, since there
is nothing to copy.  So, for some reason, something failed between
cp(1), acl_is_trivial_np(3) and the kernel.

What does "ls -al /usr/local/tinderbox/scripts/lib/buildscript" show?
