Topaz is designed to be an easy format for scanned books - it's got the images on the page, combined with a often-not-very-good OCR'd copy of the text for searching. Those scripts only get you that OCR'd text.
If your resulting book was the same, with no blatant OCR errors and with formatting intact, you're lucky.
