In general, if you want to compare two versions there's "vercmp".
This varies between different backends, in how versions compare.

$ python
 >>> from smart.backends.rpm.rpmver import vercmp
 >>> vercmp("2.3.1-77.4", "2.3.1.60svn20100810-85.1")
-1

There's also two helpers called "splitarch" and "splitrelease",
which splits out an arch or a release from a version string.

$ python
 >>> from smart.backends.rpm.rpmver import splitarch, splitrelease
 >>> splitarch('2.3.1.60svn20100810-85.1 at i586')
('2.3.1.60svn20100810-85.1', 'i586')
 >>> splitrelease('2.3.1.60svn20100810-85.1')
('2.3.1.60svn20100810', '85.1')

Again, just how package architectures and release revisions are
represented as strings varies (greatly) between the backends...

name1-version1-release1.noarch.rpm
name1_version1-release1_all.deb
name1-version1-noarch-release1.tgz
name1-version1-release1-i686.pkg.tar.gz
