Problem 470. Scoring for oriented dominoes

Created by Doug Hull

Given a list of ordered pairs, and the order they should be placed in a line, find the sum of the absolute values of the differences.

list = [1 2
        5 3
        2 4
order = [1 3 2]
yields: [1 2][2 4][5 3]
    or: abs(2-2) + abs(4-5)
    or:        0 + 1
    or: 1

This problem is associated with the MATLAB Tiles Contest running from April 4th to April 11th.
