How to put a random number in the title field?

Hi everyone, I love this wonderful software that mp3tag is, but when it comes to scripting I really suck!
I use a USB key to play music in my car and I noticed that the player plays in alphabetical order of the title field. Since it uses the file name as display name I already renamed all that, and now I would like to write random numbers in the title field in order to randomize the playlist a little bit. Could you help me with that please?

You could do one of the following.
Load the files into MP3tag.
Click on the top left column header. This arranges the files in a random order.
Now you could rename the files with:
Convert>Tag-Filename
%_counter% _ %_filename%

Or you rename them straight away with the Convert>Tag-Filename function:
$rand() _ %_filename%
or even
$num($rand(),5) _ %_filename%

Hey, thanks for your reply. However I do not want to change the filename, I want to change the title.

As you mentioned both ...

Use an action of the type "Format value" for TITLE
Format string: $rand() _ %title%
