title: Code an Excel VBA sort with a custom order and a value containing commas
body: <p>In VBA, Excel allows sorting values using the CustomOrder parameter to choose the sequence items are ordered. Unfortunately, the sequence of items is delimited by commas and one of my sort items contains commas. For example, I want to sort the data in the first column by the categories in the second column. The "Air, Land, or Sea" category contains commas.</p>
  
  <blockquote>
  <pre>Data1     Aerospace
  Data2     Cyberspace
  Data3     Cyberspace
  Data4     Air, Land, or Sea
  Data5     Aerospace
  Data6     Air, Land, or Sea
  Data7     Cyberspace
  </pre>
  </blockquote>
  
  <p>If you record a VBA macro, the code created looks like this:</p>
  
  <pre><code>MyWorksheet.Sort.SortFields.Add Key:=Range( _
      "B:B"), SortOn:=xlSortOnValues, Order:=xlAscending, _
      CustomOrder:= "Cyberspace,Air,Land,or Sea,Aerospace", _
      DataOption:=xlSortNormal  
  MyWorksheet.Sort.Apply
  </code></pre>
  
  <p>So, the custom sort order should be "Cyberspace" then "Air, Land, or Sea", then "Aerospace". However, the second category is treated as three categories because of the commas.  The rows with "Air, Land, or Sea" get sorted to the bottom because Excel doesn't find a custom sort match for them.
  Is there a way to get CustomOrder to work with a category that contains embedded commas?</p>
  
  <p>I tried putting double quotes around the category and I tried replacing the delimiter commas with semicolons (in the hope Excel would accept a semicolon instead of a comma). Neither worked.</p>
