The word סופר means both author and counter. "The authors" used to be writers of holy scrolls, where they would be copying over from an older source.
When done they would count the letters to make sure that the scroll is complete (this is still practiced nowadays, though done by computer). An incomplete scroll could not be used, even if missing one letter.
That's sort of a connection.
Hence the very dark joke:
What did Eichmann and Bialik have in common?
שניהם היו סופרים יהודים.
