I think you are running into order of interpolation issues, and some of 
your code was in disrepair.  Try the (untested) changes I made 
below.  Also, you might try out [table-organize], I have found it very useful.

Best,

- [seti col_count]0[/seti]
+ [item-calc]$Scratch->{col_count} = 0; return;[/item-calc]

Change this to [item-calc] as well.

This would be

[item-calc]

        if ( $Scratch->{col_count} < 4 ) {
                # Do nothing?
        } else {
                $Scratch->{col_count} = 0;
                # return html stuff
        }

[/item-calc]
