how about:
<%
@medicine.grouped_stocks.each_pair do |k, v|
v.sort_by {|stock| stock.amount_on_hand}.each do |stock|
%>
<%= "#{stock.medicine.name} #{stock.strength} #{stock.route.name}
#{stock.amount_on_hand}" %>
<%
end
end
%>
not sure if that will sort ascending or descending though... if it's
the wrong way round, you can always reverse before you .each...
