Ranking of most theocratic nations on earth?

Are there any rankings on theocratic nations, how they force their population to adhere to some "god-said-so" rules?

I guess Afghanistan and Saudi Arabia would lead such a ranking.

1. Afghanistan
2. Saudi-Arabia

???

I guess most nations leading this will be muslim. At some point the Russia (orthodox Church) US (evangelicals) and Israel (Zionism) might follow. Europe, Scandinavia, might be the most free on earth in regards to Theocracy, performing as well as Japan and South Korea.
