In reading some of the Summa Theologica with my children today, I noticed a difference in the translations which answers your question precisely!
In this older version of the Summa, the translation reads: “One of these is ‘sin,’ which is opposed to virtue in respect of that to which virtue is ordained: since, properly speaking, sin denotes an inordinate act; even as an act of virtue is an ordinate and due act:…”
In my “newer” (1941) version, these words are replaced with “ordered” and “disordered.”
The meaning if the word is (possibly) illuminated by reading the entire linked article, but overall, to be ordered, the thing or act must be in accord with its nature which includes its “end,” (goal or purpose).
As an example, sometimes I want to remove a screw and don’t feel like looking for a screwdriver so I use an old dinner knife. Now, that is not what the knife is meant for: unscrewing things is not its “end.” Using it that way could damage it–leave knicks on the tip and even twist or weaken it as it is not designed to absorb the torque or rotary pressure the way a proper screwdriver is.
I would never do this with, say, an antique silver dinner knife from a set which has been handed down intact through several generations (aside from the fact I don’t have a set like that ;)).
So “ordered” and “disordered” are in themselves neutral words. However, disorder in humans makes them more important, because humans are more important.
As to intrinsic, it too is a neutral word in and of itself: it just means inherent, or an essential part of. A screwdriver is intrinsically able to absorb the torque of removing and replacing screws.
