If <ol> is no more and no less ordered than <ul>, what's the purpose of its introduction?
The real purposes, in the dawn of HTML, were that <ol> and <ul> correspond to numbered and bulleted lists, respectively, reflecting two very common concepts in word processors. This is how they have been used, though some authors have started overusing <ul> for thinks like lists of links even when they specifically don't want them to appear as bulleted. Even W3C specifications, in their markup, switch to <ul> in the midst of hierarchy when they want bullets and not numbers.
HTML5 tries to stick to the theoretical idea of "ordered" vs. "unordered" list, but it does not really change anything, and it is not supposed to change anything - any <ul> will still be rendered in the order written.
