Included is my attempt at doing it. It seems to be working perfectly.
You'll find a test unit called ImprovedJvListView where I simply created a descendant of TJvListView for testing the proposed changes, and, a small app to demonstrate it works.
Then, you'll find my proposed additions already included in the SVN version of JvListView.pas unit, all my changes in that unit marked "DT".

1- I could not resist the temptation in one place to clarify the code by renaming a variable ("Index" which is very unclear into "ColumnIndex" which is much clearer).

2- I also added one small other functionality that I could not find and that would be useful: a variable that indicates which colum is currently sorted. This way, we can save that value, for example in the registry then restore it when re-launching an application. It's called FSortedColumnIndex".
