A feature request?, See e.g. here:

> Hello, I use the auto-numbering wizard and I have it setup to add a leading zero when needed. I have noticed that in some cases it fails to add the zero, it happens rarely and I can't see anything different about the files. I will greatly appreciate your response and I apologize if this has been covered before; I searched for numbering, wizard, etc. and could not find any reference to this.

and as it is not forbidden and most other players can cope with it and only Microsoft has refused to iron out the strange interpretation of track numbers being octal values, I see no harm.
