I got two different sorted values when I passed the ascending arguments in the list format of booleans in string and boolean formats. I expected to run into an error if I passed Boolean values as strings. But the code got executed without any error. How do the booleans in string 'True','False' differ from boolean True, False values in execution?

A non-empty string evaluates as True, so in your case it is similar to running:
sorted_varieties = price_extremes.sort_values(by=['min','max'],
ascending=[True, True])
