I do not think this is a big problem. The kernels are different too,
though the only difference is a 3,4 and 5. The kernels are packed, so
perhaps the number 3 is used a lot more in the kernel than the number 4,
and therefore packed better. 

Another wild guess is that gzipping zips a bit different every time. I am
not sure of this, but I have heard that some packagers (powerpacker, DMS)
pack different every time.


You should try something like this:

#make-kpkg clean
#make-kpkg --append-to-version -tao4 kernel_image
install kernel
note the size
delete the kernel

#make-kpkg clean
#make-kpkg --append-to-version -tao4 kernel_image
install kernel
note the size
delete the kernel

and see if the sizes change.
