There are two scenarios, but only one RPM. Obviously you cannot have two 
RPM - one for upgrades and one for clean install.

And such script:
%pretrans
if [ -e /some/broken/file ]; then
   ....
fi

will obviously fail when you are installing to clean chroot (or bare metal).

And as Neal stated, the %pretrans is executed always. No matter if it is 
upgrade or clean install. So you need to do the check if it is upgrade 
inside of that scriptlet.
