Can pages be rearranged/merged automatically to restore odd even sequence after one-sided scans of double sided documents

Question

I would like to scan into pdf format some documents that are deteriorating badly.  These documents are printed on both sides and there are lots of them.  The stack of documents can be placed in a regular feeder scanner but only one side of the documents will get scanned at one time.  I could then turn the stack upside down and scan the other side.  But that would leave me with a grouping of the odd pages pages of the documents as pdf, and a grouping of the even pages.  How could I then rearrange/merge the pages so they appear as a normal sequence of odd-even in the pdf? Thanks.

Hey all:
Thanks for the positive feedback. I found myself needing to do some collating and reversing again, and discovered that the script didn't show up in Acrobat 9. So I updated the script, and moved the menu item into the "Document" menu.
Unfortunately I can't figure out how to attach the updated script in the new form editor, so I'll inline it. Copy the following script into a file and install it into your Javascripts folder, as before.
// Complements: Planet PDF (http://www.planetpdf.com/)
// Modified by Jeff Baitis for Acrobat 9 compatibility
// Improved Collate function with status bar.
// Add a menu item to reverse all pages in the active document
app.addMenuItem({ cName: "Reverse", cParent: "Document", cExec: "trustedReversePages();", cEnable: "event.rc = (event.target != null);", nPos: 0 });
app.addMenuItem({ cName: "Collate", cParent: "Document", cExec: "trustedCollatePages();", cEnable: "event.rc = (event.target != null);", nPos: 0 });
trustedReversePages = app.trustedFunction(function()
  app.beginPriv(); // Explicitly raise privileges
  var t = app.thermometer;
  t.duration = this.numPages;
  t.begin();
  for (i = this.numPages - 1; i >= 0; i--)
    t.value = (i-this.numPages)*-1;
    this.movePage(i);
    t.text = 'Moving page ' + (i + 1);
  t.end();
  app.endPriv();
// Collating pages

trustedCollatePages = app.trustedFunction(function()
  app.beginPriv(); // Explicitly raise privileges
  // create an array to use as the rect parameter in the browse for field
  var arRect = new Array();
  arRect[0] = 0;
  arRect[1] = 0;
  arRect[2] = 0;
  arRect[3] = 0;
  // create a non-visible form field to use as a browse for field
  var f = this.addField("txtFilename", "text", this.numPages - 1, arRect);
  f.delay = true;
  f.fileSelect = true;
  f.delay = false;
  // user prompted to select file to collate the open document with
  app.alert("Select the PDF file to merge with")
  // open the browse for dialog
  f.browseForFileToSubmit();
  var evenDocPath = f.value;
  var q = this.numPages;
  var t = app.thermometer;
  t.duration = q;
  t.begin();
  // insert pages from selected document into open document
  for (var i = 0; i < q; i++) {
      var j = i*2;
      this.insertPages(j, evenDocPath, i);
      t.value = i;
      t.text = 'Inserting page ' + (i+1);
  t.end();
  // remove unused field
  this.removeField("txtFilename");

Have fun
