[JS][CS4]PDF Export With RegExp Doesn't Include First Zero-Please Help

Question

This is a script we put together with the help of Jongware, Shonkyin and Kaysan a while back...
Here's the link to the original thread:

( function() {
if(app.documents.length != 0){
var myFolder = app.activeDocument.filePath;
if(myFolder != null){
var myPageName, myFilePath, myFile;
var myDocument = app.activeDocument;
     //var myBaseName = myDocumentName + "_" ;
          //1.  Update modified links, find and alert operator of missing links.
          var linksLog = updateLinks(myDocument, "");
     if (linksLog != "") {
          alert("Missing Links\n" + linksLog + "\nPlease resolve and try again.");
          return;
     function updateLinks(doc, log) {
          var myLinks = doc.links;
          for (var j = myLinks.length - 1; j >= 0; j--) {
               switch (myLinks[j].status) {
                    case LinkStatus.normal :; case LinkStatus.linkEmbedded : break; // nothing to do
                    case LinkStatus.linkOutOfDate : myLinks[j].update(); break; // update
                    case LinkStatus.linkMissing :
                         log = log + "Link '" + myLinks[j].name + "' is missing\n";
                    break
               } // end switch
          } // end for
          return log
     } // end updateLinks
var my_suffix = decodeURI(app.activeDocument.name).replace(/^(\d+).*/, '$1');
//my_suffix = Number(my_suffix);
if (typeof (my_suffix) != 'number')
my_suffix = Number(my_suffix);
for(var myCounter = 0; myCounter < myDocument.pages.length; myCounter++){
    if (myDocument.pages.item(myCounter).appliedSection.name != ""){
        myDocument.pages.item(myCounter).appliedSection.name = "";
myPageName = myDocument.pages.item(myCounter).name;
app.pdfExportPreferences.pageRange = myPageName;
myFilePath = myFolder + "/" + "MyTest_" + (my_suffix + myCounter) + ".pdf";
myFile = new File(myFilePath);
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract;
myDocument.exportFile(ExportFormat.pdfType, myFile, false, "[Press Quality]");
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
    else{
        alert("No documents are open. Please open a document and try again.");
        exit();
alert("Finished exporting");
The problem is, I never considered pages 0 through 99. The script works perfect for 138-140 TEST 10_WORKER.indd. It creates PDFs named:
MyTest_138.pdf
MyTest_139.pd
MyTest_140.pdf
If the document name is 098-100 TEST 10_WORKER.indd, It creates PDFs named:
MyTest_98.pdf -  should be MyTest_098.pdf 
MyTest_99.pdf -  should be MyTest_099.pdf 
MyTest_100.pdf - This is perferct
And of course, the double 0s, 008-010 TEST 10_WORKER.indd
MyTest_8.pdf -  should be MyTest_008.pdf 
MyTest_9.pdf -  should be MyTest_009.pdf 
MyTest_10.pdf -  should be MyTest_010.pdf 
Why doesn't it use the first 0(s) in the name? 0 is a digit and every RegEx tester I've checked it with includes the zero.
Any assistance with getting this script to use the leading zero if there is one would be greatly appreciated.
Also, if there is a way to export each PDF from a multipage document which doesn't start with a number, it would be extremely helpful.
Thanks in advance

The zeros aren't there because they never were there. Your loop starts at 0 and that could be a page number. To pad your page numbers to three-digit numbers, replace this line:
myFilePath = myFolder + "/" + "MyTest_" + (my_suffix + myCounter) + ".pdf";
with this one:
myFilePath = myFolder + "/" + "MyTest_" + (my_suffix + pad(myCounter)) + ".pdf";
and add the following function somewhere at the end of your script:
function pad (n) {
    return ("00000"+n).slice(-3);
