ASP Sort MS Access Query by Ascending Date

I have written a script which selects distinct dates from a database and populates them into a combo box.  See script below:

                        ' Get distinct date values
                        set rsD = Server.CreateObject("ADODB.Recordset")
                        response.write "<select name=date_select><option selected>None Selected</option>"
                        mSQL = "SELECT DISTINCT tbl_master.Date FROM tbl_master ORDER BY tbl_master.Date;"
                        rsD.open mSQL, fso
                        do while not rsD.eof
                            if not rsD.eof then
                                Response.Write ("<option value=" &rsD("Date")& ">" &rsD("Date") & "</option>")
                            end if
                            rsD.movenext
                        loop
                        response.write"</select>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"
                    %>

What happens, is the dates are sorted, but not really in ascending order.  See attached screen shot:


How can I sort these records in true ascending chronological order??
