You can easily see that if you have two items while "Sort Articles" is enabled, one with "Thin Man 2" and another with "The Thin Man" in the Sort Title field. "The Thin Man" is erroneously collated before "Thin Man 2". It seems to me that "Sort Title" should work like the regular title field with respect to articles.

My understanding is that the "sort" fields override the behaviour of the primary fields they're attached to. It allows you to sort *exactly* in the way you pleased, and to do that it makes no assumptions...such as ignoring articles.
