I don't think this is too much code to expect people to write:
$row{__selected__} = "selected" if $value;
That's really all you're talking about, right?

Because CGI.pm already has it nailed. Why reinvent the wheel? And
you can't beat the simplicity:
$template->param(year_select =>
scalar $query->popup_menu(-name => 'year',
-values => [ 1970 .. 2020 ])
);
And in the template:
<tmpl_var year_select>
I've been doing it for years now and it's never done me wrong.
