Custom order for taxonomy?

Any advice on how I could display the terms in a custom order rather than alphabetically?

This is how I’m displaying the terms currently:

add_action( 'genesis_before_loop', 'nabm_isotope_filter' );
function nabm_isotope_filter() {
	if ( is_post_type_archive( 'videos' ) )
		$terms = get_terms( 'topic' );
		$count = count($terms); $i=0;
		if ($count > 0) { ?>
			<ul id="video-cats" class="filter clearfix">
				<li><a href="#" class="active" data-filter="*"><span><?php _e('All', 'genesis'); ?></span></a></li>
				<?php foreach ($terms as $term ) : ?>
					<li><a href="#" data-filter=".<?php echo $term->slug; ?>"><span><?php echo $term->name; ?></span></a></li>
				<?php endforeach; ?>
			</ul><!-- /video-cats -->
		<?php }
}
