To style lists, you'll just need to add a little bit of CSS. The following CSS code makes ordered lists look nice and is from http://codeitdown.com/ordered-list-css-styles/.

You can add the following style code to source/_includes/custom/head.html by surrounding it in <style type="text/css"></style> tags.

ol {
    list-style-type: none;
    list-style-type: decimal !ie; /*IE 7- hack*/

    margin: 0;
    margin-left: 4em;
    padding: 0;

    counter-reset: li-counter;
}
ol > li{
    position: relative;
    margin-bottom: 20px;
    padding-left: 0.5em;
    min-height: 3em;
}
ol > li:before {
    position: absolute;
    top: 0;
    left: -1.33em;
    width: 1.2em;
    height: 1.2em;

    font-size: 2.5em;
    line-height: 1.2;
    text-align: center;
    color: #f5f5f5;

    border: 3px solid #c5c5c5;
    border-radius: 50%;
    background-color: #464646;
    content: counter(li-counter);
    counter-increment: li-counter;
}
