<select>
<option>opt1</option>
<option style="text-align: right;">opt2</option>
<option>opt3<div class="right">I need to be to the right</div></option>
</select>
By using the CSS text-align: right;
this what you mean?
Ugly alternative:
<select>
<option>opt1</option>
<option>opt2</option>
<option style="text-align: right;">Foo Bar </option>
</select>
It will "more or less" make the letters in-between space bla ect, not even sure what to call this. :)
