I am in Canada so it's not always the same.
I took out an RRSP loan (hey, 2.85% interest rate (prime) versus 6.5% on my personal LOC). They had to pull my credit score to do it - 769 (apparently max is 800 for wherever they pulled it). Bills paid on time, no overdues or too much on CCs, one credit check in the last 2 years (when I rented an apartment for a year). The loan officer seemed to think that 769 was pretty good, he never sees an 800, and isn't sure what you would have to do to have it. Oh, and he is one of us without knowing it, plans to be retired by 35.
Credit scores are not something I have ever really worried about - leading a mustachian life pays off. I haven't found being retired is an issue either, as long as there is income coming in from somewhere they don't seem to care where it comes from. However, we don't have the CC churning opportunities that people in the US have, so credit scores only really matter for the biggies - mortgage, car loan (I am talking general population, not us), CCs.
