They contain text, so the OCR problem is out of the way.
Sadly, the text is re-arranged so the optimal solution (one
line in a table equals one line of text, with the columns
being separated by whitespace) does not appear, instead it
is the other way round: one line equals one column.

I'd suggest something like this:
pdftotext <file> | ... | paste | ... | sort | uniq -d | wc -l
This will probably almost do what you need, given sufficient
assumptions... :-)
