"Reverse Alphabet Codes"

Given the following information:

a = 26, b = 25, c = 24, d = 23 ..... x = 3, y = 2, z = 1

What is the sum of each letter of this sentence: "The quick brown fox jumped over the cow"? (Note, a white space has no value).

You can simply reuse the code from challenge 4 and modify it to use these numbers, then change it to it does addition rather than multiplication.
