Non-database dropdown select - works fine, but why the weird order?

I have built a select_tag dropdown to represent a group of selections that will feed a model-query routine I've written. This routine works fine but the order of the items is different than what I programmed. My objection to this order is that I want the 'All => ''' to be on the top. Here it is;

        <tr>           <td><strong><%= "User Module" %></strong></td>           <td> <%= select_tag(:module, options_for_select('All' => '', 'Evidence' => 1, 'Assets' => 2, 'Inventory' => 3, 'Water' => 4, 'Laboratory' => 5, 'State EPA' => 6, 'Administrator' => 7), :style => "width:206px", :id => :indexselect) %> </td>         </tr>

and here is the order of items as they 'drop down' on the form.

Laboratory All Administrator Assets Water Evidence Inventory State EPA

I am grateful for any suggestions. Kathleen

Hashes in Ruby do not keep the insertion order, you should do it like this:

<%= select_tag :module, options_for_select( [ ['All',''], ['Evidence' , 1], ['Assets', 2], ['Inventory', 3], ['Water' , 4], ['Laboratory' , 5], ['State EPA', 6], ['Administrator', 7]]), :style => "width:206px", :id => :indexselect %>
