More sensible duplicate file name naming.

Right now when I download multiple different files that have the same name...RMC4 prefixes:
copy of <file name>.<extension>
copy (<#>) of <file name>.<extension>

The problem I'm running into is that I'm looking to rename the files and preserve order of download.

I'm using an application called Flash Renamer...but this likely applies to other file renaming applications as well.

Anyways an example: (as appears in the app)
2011-04-22.wmv
copy (2) of 2011-04-22.wmv
copy (3) of 2011-04-22.wmv
copy (4) of 2011-04-22.wmv
copy of 2011-04-22.wmv

The problem however is that the display order above is:
1
3
4
5
2

And well I need 1-5 in order.

The problem gets worse if there are multiple sets.

So would it be possible to talk you guys into doing it like so:
2011-04-22.wmv
2011-04-22 (2).wmv
2011-04-22 (3).wmv
2011-04-22 (4).wmv
2011-04-22 (5).wmv

It would also be nice to have the option to zero pad the incrementing value, should it climb into double or triple digits. As I run into the following display issue with my file renaming application.

Example:
2011-04-22.wmv
2011-04-22 (10).wmv
2011-04-22 (11).wmv
2011-04-22 (12).wmv
2011-04-22 (13).wmv
2011-04-22 (14).wmv
2011-04-22 (15).wmv
2011-04-22 (16).wmv
2011-04-22 (17).wmv
2011-04-22 (18).wmv
2011-04-22 (19).wmv
2011-04-22 (2).wmv
2011-04-22 (3).wmv
2011-04-22 (4).wmv
2011-04-22 (5).wmv
2011-04-22 (6).wmv
2011-04-22 (7).wmv
2011-04-22 (8).wmv
2011-04-22 (9).wmv

Which with Zero Padding would look like this:
2011-04-22.wmv
2011-04-22 (02).wmv
2011-04-22 (03).wmv
2011-04-22 (04).wmv
2011-04-22 (05).wmv
2011-04-22 (06).wmv
2011-04-22 (07).wmv
2011-04-22 (08).wmv
2011-04-22 (09).wmv
2011-04-22 (10).wmv
2011-04-22 (11).wmv
2011-04-22 (12).wmv
2011-04-22 (13).wmv
2011-04-22 (14).wmv
2011-04-22 (15).wmv
2011-04-22 (16).wmv
2011-04-22 (17).wmv
2011-04-22 (18).wmv
2011-04-22 (19).wmv

** Edit **

Okay while the above suggestion should be implemented...I have since ran into situations where the base file name subverts the order of download. So I'd like to suggest the option to prefix all downloads with zero padded increments.

The problem arises when I download Carrot.flv then download Apple.flv since A comes before B my download order is now screwed. However "01 - Carrot.flv" will always come before "02 - Apple.flv"
