Bug in Indesign CS4 Character Styles All Small Caps?

So I was using my Williams Caslon font to set a book, and decided to use the "all small caps" option. This was to access the (ahem) very cool feature of special small caps figures and parens, to create discrete citations for display quotes.

I tried at first setting up a "character style" to do this, as in that dialogue box you have the option of choosing "open type all small caps". But when I saw the result, I freaked out, because the numbers were too small, and there was no kerning to the colon, and it looked a wreck.
