The length of articles itself isn't an issue. The ability for the readers to quickly find and narrow down the information that they want is more important.
FrankLeeceo beat me to the punch but i'll expand regardless (on my opinion for whatever it's worth.)I don't think the length of the article is the issue, I would wager people are looking for a quick answer and that your user metrics (bounce rate, CTR, etc) are lower than theirs. Or at least a handful of your past traffic was looking for a quick answer.
Like viral said, you probably did nothing wrong, just think about the user experience on the page. As FrankLeeceo said, can they find what they are looking for right away? That may be a good reason to break it up into two or three sections.
Also, like viral said "Google is looking for freshness these days". I don't know how long you've been outranked by the scraper site but maybe their just benefiting from being a new site and will drop down soon?
