IIR still confuses me!!!

[Desert_Eagle]

I don't get where you find the friggin' scoretag for IIR! I've been playing the arcade machine and gotten good enough scores to post on, but I can't figure out what this is!!! There needs to be an in-depth explanation to the score tag, because what's going on in my head is I can put in any said number and it will generate my score. I don't get that! How in the world do i activate my account? Where do I find said scoretag? Was I given a scoretag previously? Please explain to me!!

EDIT: It's been 3 days and nobody has answered me. How long will the pain go?! I am still confused!!!
