Feels strange replying again, but I thought about it for a bit and using Javascript sucks, so here's a slightly different take on doing it with the template.

use HTML::Template;

my $tmpl = q{
    <TMPL_LOOP NAME=OPTIONS> 
        <option value="<TMPL_VAR NAME=VALUE>" <TMPL_VAR NAME=SELECTED>
+><TMPL_VAR NAME=TEXT></option>
    </TMPL_LOOP>
};

my @options = ();

for (0..5) {
    push @options, { 
        VALUE       => $_, 
        SELECTED  => $_ == 3 ? 'selected' : '',
        TEXT        => {  0 => ' any',
                          1 => ' one day',
                          2 => ' two days',
                          3 => ' three days',
                          4 => ' four days',
                          5 => ' one week',
                         }->{$_},
    };
}

my $t = HTML::Template->new(scalarref => \$tmpl);
$t->param(OPTIONS => \@options);
print $t->output;
