You can do it in a query, of course, using SQL.

In a search-list, you would need to display all of the items with a ml=9999
or somesuch.

Then:

[search-region]

    [search-list]
	[item-calc]
		$all++;
		$total{'[item-field category]'}++;
		return;
	[/item-calc]
    [/search-list]

    [on-match]
	[calc]
	    my @out;
	    for (keys %total) {
		my $pct = $total{$_} / $all * 100;
		push @out, sprintf("%.1f%% in category %s", $pct, $_);
	    }
	    return join ", ", @out;
	[/calc]
    [/on-match]

[/search-region]

Few blame themselves until they have exhausted all other possibilities.
