You may have a look at my ObservableView implementation which wraps an observable collection (or other list) and provides "live" ordering and filtering:

If the result of sorting/filtering is IEnumerable<T> then you can just create another ObservableCollection and pass result as a parameter to constructor

Probably for the sort you can convert it to a List and then call Sort(), providing a comparison delegate. Something like:-

my_collection.ToList().Sort((left, right) => left == right ? 0 : (left > right ? -1 : 1));
