There are a number of OCR applications in the App store but I have not found any that begin with a Tiff, jpeg, etc image. Instead they all start with a PDF. However, Adobe Acrobat, PDF Pen, PDF Pen Pro, Evernote and several others will work from a PDF image and all of them can with some degree of success, convert the OCRed output into some Word compatible output. Often requiring a substantial bit of editing to get the format close to correct.
You might start by using Graphic Converter 9 to convert the Tiff to PDF and yarn using one of the aforementioned applications OCR the resulting PDF file. If you have the printed image and a scanner, Graphic Converter can drive the scanner and go direct to PDF. Evernote can drive the scanner to drive the document and go directly to OCR PDF text.
