Ummm, %name is pkg dependent, as you have discovered.

Of course they don't work, --eval is immediate.
Try (if you must, there's certainly easier ways to get a path):
rpm --define "name `rpm -q --qf '%{name}' --specfile /path/to/specfile.spec`" --eval '%{_sourcedir}'

Modulo typos and quoting, this should display the path that you desire.
