The [counter] tag won't generate random numbers for you.

You could create a UserTag like this:

    UserTag generate_key Order length
    UserTag generate_key Routine <<EOR
    sub {
        my $length = shift || 1;
        my $out;

        $out .= int(rand(10)) for (1 .. $length);
        $out;
    }
    EOR

...and call it like this: [generate-key length=3]

Once you have the number, you can put it into the database table
in any way you see fit.
