Suppose I am upgrading a package foo-1.0 to foo-2.0 (assume foo is not relocatable), and both packages have %preun sections in their .spec files. It appears that foo-1.0's %preun is run after foo-2.0 has been installed. So what happens if foo-1.0 needs to run a binary that was provided as part of foo-1.0 during its %preun stage, and a binary of the same name is provided with foo-2.0? The installed binary is now foo-2.0's, right? So how to run foo-1.0's binaries during its %preun stage? Is the old binary available under a different name before it gets erased?

Err misread the question a bit there... The new binary will be there....
You can always copy the old binary in %pre to /tmp something to have in %preun and then remove it afterwards...
%pre is before files get replaced...
