Sorting (orderby) more than one field in a loop

Is there any way to have a secondary (and tertiary) sort field? I would like to add stc_model as the secondary sort to the loop below.

[loop type=stc taxonomy=stc_type term=rvsm orderby=stc_make order=asc]
<tr>
<td>[field stc_make]</td>
<td>[field stc_model]</td>
<td>[field stc_number]</td>
<td>[field stc_ica]</td>
<td>[field stc_afms]</td>
</tr>
[/loop]
