The counters section in CSS 2.1 specifications contains various examples of how to implement your custom counter. Here is a very simple example where you:

1. Define a counter variable
2. Increment it for specific elements (in your case it would be .count elements)
3. Display it inside pseudo elements

.custom-counter {
  /* define a counter variable */
  counter-reset: clumsycount 0;
  /* style */
  list-style-type: none;
}
.custom-counter .count {
  /* increment the counter variable */
  counter-increment: clumsycount 1;
  /* style */
  position: relative;
  background-color: #EEE;
}
.custom-counter .count:before {
  /* display the counter variable */
  content: counter(clumsycount) ".";
  /* style */
  position: absolute;
  top: 0;
  right: 100%;
  padding-right: .25em;
  background-color: #CCC;
}

<ul class="custom-counter">
  <li class="count">one</li>
  <li class="count">two</li>
  <li class="count">three</li>
  <li class="count">four</li>
  <li>blabla</li>
  <li class="count">five</li>
  <li class="count">six</li>
  <li>blabla</li>
  <li class="count">seven</li>
</ul>
