Automator - When using the Render PDF as Image action, the first file is out of order (naming). How can I fix this?

Question

I am creating an Automator Action to render PDF files as Images.  When the PDF is multiple pages, the first page has no numbers, so it ends up at the end of the list.  Here's an example:
When it is a single page, the result is:
filename.png
When it is multiple pages, the result is:
filename 141.png
filename 142.png
filename 143.png
filename 144.png
filename.png
First, it always seems to start at 141...not sure why.
Second, I did try to add an action to rename and make sequential, however the resulting list was in the same order... except with additional numbers at the end.
Any suggestions?

Answer 1

I see. 
This worked when I tested on 1 PDF:
The Run Shell Script Action is:
basename=${1##*/}
echo ${basename%.*}
If it's still out of order, add: Sort Finder Items [by creation date] after Render PDF Pages as Images
