Find a specific Sublayer and move to top level layer

Question

I have a lot of illustrator files that are organized by a template size. The layers are setup so that the top level layer is always Template. However the sublayer I need to move to the top level could be called 42 Pg Border or 30 Pg Border or 24 Pg Border.
Is there a way for a script to search through the layers and if it finds "42 Pg Border" or "30 Pg Border" or "24 Pg Border" in the sublayer Template it would move it to the top level but if it doesn't see one of those it doesn't give an error?
I'm still new to scripting so the extent of my knowledge on this is to scan all the layers and unlock them. Then look for a specific layer name. It's the sublayer and moving it to the top level that I am not sure of.
Here is my current code:
var doc = app.activeDocument;
var allLayers = doc.layers;
for (var i = allLayers.length-1; i >= 0; i--){
    allLayers[i].locked = false;
    if (allLayers[i].name == "42 Pg Border" || allLayers[i].name == "30 Pg Border" || allLayers[i].name == "24 Pg Border") {
        alert("I found the " + allLayers[i].name + " layer")
    } else {
        alert("Not the right layer")
Any help would be greatly appreciated!

OK so that code is really close! I tweaked it a bit. I kept getting an error that said cannot move a locked layer. So I just made a loop to unlock ALL the layers first thing. Then to get rid of some of the "extra" code I wrote I changed this line:
if (layer.name == "42 Pg Border" || layer.name == "30 Pg Border" || layer.name == "24 Pg Border") {
to this.....
if ((layer.name).substr(-6) == "Border") {
So now instead of looking for 42 30 24 (and other border templates I may have to add) I just told it to look at the 6 characters at the end of the string (which will always be the word Border).
OK so now the code runs and does what it is supposed to but I am getting an undefined in my javascript console in extendscript. Any ideas?
Current updated code:
var doc = app.activeDocument;   
var allLayers = doc.layers;  
var count = 0;
for (var z = allLayers.length-1; z >= 0; z--){
    allLayers[z].locked = false;
for (var i = allLayers.length-1; i >= 0; i--){ 
deeper(allLayers[i]);
  if (count == 0){ 
     alert("No Border Layer Found"); 
function checkLayer(parent,layer){    
    if ((layer.name).substr(-6) == "Border") {   
  layer.move(allLayers[0],ElementPlacement.PLACEBEFORE); 
        ++count; 
function deeper(parent){ 
var subLayers = parent.layers; 
  if (subLayers.length > 0){ 
  for (var i = subLayers.length-1; i >= 0; i--){   
  checkLayer(parent,subLayers[i]); 
  if (count>0){return} 
  deeper(subLayers[i]); 
  } return
