If you ping authorship on article "How to build a house" at 12:05, and scraper site steals your article and changes title to "Building a house - simple way" at 13:05, and creates a ping for authorship, if the scraper site has higher PR or more traffic, it could easily outrank you. Google does not read content to compare it. Most probably, it takes other paramters like PR, links, web brand etc. to decide on which position will this article be placed. Your article and stolen article are the same, but they have different author and if Google doesn't read them, both are perfectly legit and different. Then other parameters decide.
