What is the exact name of your RPM?  If it's just "python", then maybe
yum is trying to upgrade CentOS' "python" to yours, which would be bad
news.  You could call it "python2.5" or even something like
"python2.5-custom" to be extra safe.

(We build a ton of third-party RPMs, and most of them have our company
name in the RPM name precisely to avoid name conflicts with Red Hat or
CentOS builds of the same upstream software.  And I am slowly switching
the old ones, that do not have our company name in them, over to that
naming scheme.  It just makes everything work more smoothly.)
