Usually when OCR an table of content the columns are separated by a large space, so the outputs are not properly order. For example, for an table like this:
The output would be:
The Rank Function
Permutations of Atoms
Pure Set Theory and Axiom System ZF
3.5
3.6
3.7
I'd like it to be:
3.5 The Rank Function112
3.6 Permutations of Atoms116
3.7 Pure Set Theory and Axiom System ZF118
But different TOCs has different the output patterns, so there is no way to build a regex script to automatically fix every book. The best approach is to fix it at the first place. But how?

Define what is: "fix it at the first place".
If you want to fix wrong output from OCR analysis, a simple solution on an infinite set of TOCs you will never make.
You will never apply all variations. You would have to create a machine learning algorithm that would analyze each TOC variant.
Or count substrings of the same characteristics (in simple TOC).

If you want to fix OCR analysis, it's a good to answer:
What OCR tool do you use?
For example, in Tesseract you can set, that text is processed by rows instead of columns.

Not really answer the question, but some books in Google Books have TOC:
