This code supposes the numbers are integers and in each list there's at least one number:

li = [['11','rt','c'],['dr','3','mn'],['fs','1','a'],['2','rt','c']]

def is_number(s):
    try:
        i = int(s)
        return True
    except ValueError:
        return False

print([li[i[-1]] for i in sorted([[int(j), ii] for ii, i in enumerate(li) for j in i if is_number(j)])])

Prints:

[['fs', '1', 'a'], ['2', 'rt', 'c'], ['dr', '3', 'mn'], ['11', 'rt', 'c']]
