There's probably a much easier way, but:

$ perl -wle'print for Win32::GetOSVersion'
Service Pack 1
5
1
2600
2

This reports:

     Win32::GetOSVersion()
         [CORE] Returns the list (STRING, MAJOR, MINOR, BUILD, ID), where
         the elements are, respectively: An arbitrary descriptive string,
         the major version number of the operating system, the minor ver-
         sion number, the build number, and a digit indicating the actual
         operating system.  For the ID, the values are 0 for Win32s, 1 for
         Windows 9X/Me and 2 for Windows NT/2000/XP/2003.  In scalar con-
         text it returns just the ID.

         Currently known values for ID MAJOR and MINOR are as follows:

             OS                    ID    MAJOR   MINOR
             Win32s                 0      -       -
             Windows 95             1      4       0
             Windows 98             1      4      10
             Windows Me             1      4      90
             Windows NT 3.51        2      3      51
             Windows NT 4           2      4       0
             Windows 2000           2      5       0
             Windows XP             2      5       1
             Windows Server 2003    2      5       2
