It looks like you have a hash of hashes. Is that correct?

Anyway, you can pass "sort" the name of the key that you want sort on.

<% FOREACH Pat IN Pats.sort('SNAME') %>
<tr class="list-group-item">
   <td width="70"><% Pats.SNAME %></td>
   <td width="75"><% Pats.ANAME %></td>
   <td width="35"><% Pats.SSN %></td>
   <td width="35"><% Pats.YR %></td>
   <td width="250"><% Pats.CHNAME %></td>
   <td width="550"><% Pats.DESCRIP %></td>
</tr>
<% END %>
