Retain original order when renaming files to number sequence?

Here's an example script with enabledelayedexpansion for renaming files:
How to write a batch file to rename files in numerically order within a particular folder?

How to retain the original file order though? I need a possible solution for Bash and for Batch (DOS/Windows).

Edit: OK - I think a specific example of my situation for batch is necessary to understand the sorting issue.
What I have are .cab files in a folder, like this:
"1_1.cab" - "1_120.cab"
I try to understand how to rename the files for the result:
"1.cab" - "120.cab"
In theory there must be a way to take care about all "1_" while renaming to achieve the original order.

possible solution for batch in this specific case:
for /F "tokens=1,2 delims=_" %%G in ('dir /b /A:-D *.cab') do rename %%G_%%H %%H

After the OP edited its question saying he only wants to strip the file names from their prefix 1_, I suggest a new solution:

for file in *; do mv "$file" "${file#1_}"; done

If the prefix can be any number followed by an underscore, it is possible to adapt this latter solution.

As far as I understand your question, I suggest you to try: 

for file in *; do ((i++)); mv "$file" "$i.${file##*.}"; done

This will rename all the not hidden files of the current directory to files having as name a number followed by the same suffixe as the original file. The numbers will respect the existing order of the files.

Also be sure you have no file having a number as basename: you risk to erase it.

If you are not sure of the result, change mv into echo mv for seing what is going to happen before you actually do it.
