Help with batch renaming

Question

I need to create a custom renaming script and just can't seem to figure it out. I'm already in Bridge CS6 with the Batch Rename dialog open.
My files are currently named as such: ABC-100-name-01
I need them to read: ABC-100-01-name
Absolutely any help is appreciated! This will be an incredible time saver.

OK, try adding this to your scripts folder… Done slighty long hand so's you can swap about if needed…
To run select Custom Rename at the bottom of the Tools menu…
#target bridge
#engine main
if ( BridgeTalk.appName == 'bridge' ) {
          var toolMenu = MenuElement.find( 'Tools' ),
          customRename = new MenuElement( 'command', 'Custom Rename', '-at the end of toolMenu', 'muppet009' );
customRename.onSelect = function () { renameFiles(); }
function renameFiles() {
          if ( app.documents.length == 0 ) { return; }
          var i, count, doc, file, parts, baseName, ext, oldName, newName;
          doc = app.document;
          count  = doc.visibleThumbnailsLength;
          for ( i = 0; i < count; i++ ) {
                    if ( doc.visibleThumbnails[i].type == 'file' ) {
                              oldName = decodeURI( doc.visibleThumbnails[i].name );
                              baseName = oldName.match( /(.*)\.[^\.]+$/ )[1];
                              ext = oldName.replace( /^.*\./,'' );
                              parts = baseName.split( '-', 4 );
                              newName = parts[0] + '-' + parts[1] + '-' + parts[3] + '-' + parts[2];
                              if ( ext != '' ) { newName += '.' + ext; }
                              file = doc.visibleThumbnails[i].spec;
                              //$.writeln( newName );
                              file.rename( newName );
