This is the package release version number, nothing to do with the thing
that is packaged.
Its purpose is to allow for this script to be used with an automated
package builder, and thus create a unique package version with each iteration,
for example using a jenkins job number instead of always being "1". Also,
having a distinct package version makes the package directly usable in a yum
repository without having to nuke the repodata because of signature mismatches
for files that were rebuild using the same name (and package version).
It is also not only the file name that is changed. If you instpect the repo
you will see it in the "Release" details:
