I was like, how do you have a score that gets you the best possible terms on a mortgage, but not on a credit card, how does this make sense. Heck if I know.
Mortgage lenders are driven by the various US gov't entities that buy most of the mortgages, and they, being polite, are morons. They care about FICO scores, and very little else beyond income qualifications.
Credit card lenders are in a more competitive market, and do much more sophisticated underwriting. FICO is used for binary yes/no decisions; limits, rates, and other account specific terms (do you get a Visa signature, or just a plat, even if you get a high limit? etc) are driven by other factors -- income, history with the issuer, apparent payment pattern on other accounts, and different weightings of the information used by fico, among others. For instance, many lenders apparently weight current history a lot higher than the FICO model does. They also tend to not care about closed accounts as much (or at all).
So Discover didn't give you a high limit, and less than the best rate, because they think they won't make money on you.
 that's the traditional FICO score that the gardeners in that other forum are so worried about. Alternative scoring comes from a number of sources; one of the big vendors: FICO. But they don't talk about that in public, because it would confuse people, and diminish the value of the brand.
