The points you got on that article are artificial points as a result of a strange bug in the system. Looking at the number of referrals and the fact that it wasn't featured on the home page, unless you had a few hundred people camping your blog (which would result in high point totals on more of your articles), you couldn't have actually achieved that number. I know it says "selected" but like I said, my post with the mysteriously large score shows around 8500 under "selected" too.
The number is not based on actual clicks or reads. You have 38 referrals total from Google on that article. You have 60 clicks from the "US Domestic" channel. You have 232 views of the article from people hitting your main blog page. You also have 23 responses (those account for about 115 points I believe at 5 points per comment). Unless those people sat there and hit refresh hundreds of times each, the number you achieved is not possible.
So they're not really your points, they're an anomaly in the point display on that article and don't track to the actual score of the article (which probably did get properly attributed to your blog score, even though the total displayed on the article is wrong). My 8500 points on my error'd blog would have doubled my overall blog score for the past 30 days
