Adding weights to Sections to order on the homepage

I’m creating an index that is ordered by section.

{{ range $section, $taxonomy := .Site.Sections }}
    <h4>{{ replace $section "-" " " }}</h4>
    <ul>
        {{ range $taxonomy.Pages }}
        <li><a href="{{ .Permalink}}"> {{ .LinkTitle }} </a> </li>
        {{ end }}
    </ul>
{{ end }}

Right now it’s ordering the sections alphabetically. I’d like to manually assign weights the same way I do to content within each section.
