Same .tar different .tar.gz

I've got two .tar.gz archives here from two different origins which differ in size,

    -rw-r--r-- 1 aham aham 606002 Apr 28 18:26 scoop_0.7.1.orig.tar.gz
    -rw-r--r-- 1 aham aham 603839 Apr 28 18:13 scoop-0.7.1.release.tar.gz

When I gunzip them, the resulting tarballs are equal in size,

    -rw-r--r-- 1 aham aham 1024000 Apr 28 18:26 scoop_0.7.1.orig.tar
    -rw-r--r-- 1 aham aham 1024000 Apr 28 18:13 scoop-0.7.1.release.tar

When I re-gzip them, they again differ in other sizes,

    -rw-r--r-- 1 aham aham 607131 Apr 28 18:26 scoop_0.7.1.orig.tar.gz
    -rw-r--r-- 1 aham aham 604502 Apr 28 18:13 scoop-0.7.1.release.tar.gz

These sizes can be recreated on my machine (by again gunzip and gzip them).

Why there are four differences in size?

Thanks in advance, DS

The tar balls may not be the same, although they are the same size.

Try running diff

diff scoop_0.7.1.orig.tar scoop-0.7.1.release.tar
