Swaziland is a good candidate for the "roundest country". Macedonia and Qatar wouldn't be too far behind either.

11, 21 and 103 respectively, according to this (table in the middle).

Hadn't see the table before my reply. I was just thinking about the countries from the ones that i remembered. Thanks for pointing me to it!

Weird, I missed it too when I first read the article, even though it is bang in the middle. They should have mentioned it in the text maybe.

possibly Poland?

Poland is mentioned as 5th in the article.
