It's the addition to answer of amaca for problems found by Allon Guralnek and VahidN. Scrolling problem is solved with setting ListView.ItemsPanel to StackPanel in XAML:

This replacement of default VirtualizingStackPanel with simple StackPanel disables automatic regeneration of internal collection of ListViewItem. So indices would not chaotically change when scrolling. But this replacement can decrease perfomance on large collections. Also, dynamic numeration changes can be achieved with call CollectionViewSource.GetDefaultView(ListView.ItemsSource).Refresh() when ItemsSource collection changed. Just like with ListView filtering. When I tried to add handler with this call on event INotifyCollectionChanged.CollectionChanged my ListView output was duplicating last added row (but with correct numeration). Fixed this by placing refresh call after every collection change in code. Bad solution, but it works perfect for me.
