Ok, searching in google, i find this solution.
I share it, if someone need it:
<?php /* The loop */ ?>
<?php $posts = query_posts($query_string . '&orderby=title&order=asc&posts_per_page=-1'); while ( have_posts() ) : the_post(); ?>
<a href="<?php the_permalink() ?>"><?php the_title(''); ?></a>
<?php endwhile; ?>

Hi, esmi. Sorry for answer you so late.
I started to modify the Twenty Thirteen theme that comes with WordPress, because it seems to me an easy start point to make the one I wanted. I’m trying to modify this on the tag.php file.

Thank you.
I’ll try this. But if I find it too difficult, maybe I’ll change using a plugin.
