Sorting in Outlook / Exchange and VBScri

How do you sort items in a listbox according
to their date? I added items in the listbox
like this:

01/01/2001:Pencils
01/05/2001:Ballpens
01/02/2001:Papers

How do I sort it in such a way that it is sequencial according to the given date? Is it possible in Outlook?
