Versioninfo resources are very complex beasts. They normally contain
strings, and numerical values as well.  I believe what you want are the
numeric version numbers in the VS_FIXEDFILEINFO structure.  There are 4
16-bit fields encoded as 2 32 bit fields, named dwFileVersionMS and
dwFileVersionLS.

The ctypes source distribution has a sample script (slightly outdated,
but it still works) in the samples/Windows/VersionInfo.py file.
