Here is a jsfiddle with a working solution.

The styles are copied here for convenience:

ol {
    counter-reset: section;
    list-style-type: none;
}
li:before {
    counter-increment: section;
    content: counters(section, ".") ". ";
}

li li:before {
    counter-increment: section;
    content: counters(section, ".") " ";
}

ol ol ol {
    counter-reset: list;
    margin: 0;
}

ol ol ol > li {
    list-style: none;
    position: relative;
}

ol ol ol > li:before {
    counter-increment: list;
    content: "(" counter(list, lower-alpha) ") ";
    position: absolute;
    left: -1.4em;
}
