This challenge is confusing. Look at what's supposed to be the answer - the 1970 movie The Land with a duration of 130 min comes before The Cruise with a duration of 66 min, while the 1960 Singapore with the duration of 158 min is placed before Jis Desh Men Ganga Behti Hai of 181 min.
Actually getting to the right sort order takes one to uncheck the "use dictionary order" in the sort. Using a string field with numbers as a sort parameter is a bad idea in general, and here it is supposed to lead one to the "correct" answer.
I am disappointed by the quality of this challenge.
