Fixing wrong version number comparison

Is there any way to override rpm's version number comparison other than
bumping the epoch?

I have perl-libwww-perl-1.0703 installed and I am trying to package the
newer version 1.09.  But rpm thinks that 1.09 is older than 1.0703.  I
have tried adding to my spec file:

Obsoletes: perl-libwww-perl = 1.0703

or the same without the '=' sign, but rpm still refuses to perform the
upgrade.

Can I persuade rpm that in this particular case, 1.09 should count as
higher than 1.0703?
