How about something like this to choose the order of files:

if( -M 'newsite1.txt' > -M 'newsite2.txt' ) {
  compare_sites('newsite1.txt', 'newsite2.txt')
} else {
  compare_sites('newsite2.txt', 'newsite1.txt')
}

That way if for some reason the update doesn't run one day, you'll still be comparing the files in proper order.
