for i in range( len( lst ) - 1 ):
    for j in range( len ( lst ) - 1 ):
        if lst [ j ] [ 2 ] < lst [ j + 1 ] [ 2 ] :
            lst [ j ] , lst [ j + 1 ] = lst [ j + 1 ] , lst [ j ]
print(lst)

Output :-

[(101, 'Portal', 3451), (103, 'Path', 3001), (105, 'Express', 2971), (104, 'Walla', 2819)]
