Apple Mail Script

I will describe an example of what I want. When I read an email in apple mail if a fedex tracking number appears on the screen it is highlighted in blue and if i click on it an internet window pops up with all the tracking info for that particular tracking number. What I want is the same thing except with my websites order numbers. Everytime a 5 digit number appears in my email i would like it to be highlighted and when i click on it an internet window opens to that exact back end order page for that order on my volusion webstore.
