You are tasked with writing the scoring algorithm for a simple word game. In this game, players will submit their word and receive back the score of their word. The goal of the game is for the players to try and figure out how to make the highest scoring words based on the scores they are getting back.

In order to score a word, you will add up the point value of each letter in the word. The word doesn't have to be a real word, just a string of characters.

The scoring system for the game is: F = 3, J = 6, X = 12, A, I, E, O = 2, T = 5 and all other letters are 0. It does not matter if the letter is upper or lower case.

You can ignore any non letter input in the string and assume the string will be at most 50 characters long.

Example 1: For the string "XRay Machine" The score would be: 12 + 0 + 2 + 0 + 0 + 0 + 2 + 0 + 0 + 2 + 0 + 2 = 20

Example 2: For the string "Jabbt" The score would be: 6 + 2 + 0 + 0 + 5 = 13
