Order in which command prompt executes files with the same name (a.bat vs a.cmd vs a.exe)

Question

What is the order in which the Windows command prompt executes files with the same name, but different extensions?

For example, I have a bunch of executable files: <

Okay, I did some quick experimentation based on some other searches I had going.

The gist is that the order of the commands is dependent on the order the extensions are stored in the PATHEXT environment variable. So initially I had:

PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.RB;.RBW

and for the example above the order in which it would run it was:

something.exe
something.bat
something.cmd

Changing the order which they were defined in the PATHEXT environment variable did indeed change the order in which they were executed.
