Alright, it took me awhile, but here's a script that I hope works to sort just the selected layers. As you mentioned, the layers will be all together, so if the selected layers aren't contiguous, the script will just move all the other layer after where ever the first selected layer is located.

var doc = activeDocument;
var bkgn = hasBackground ();
var topLayerID//To hold top selected layer ID
var lyrSelIDX = (getSelectedLayersIdx ())//indexes of selected layers
var orgLayA = getLayerSetsData(lyrSelIDX)//array of selected layer names and IDs
multiSelectByIDs (topLayerID);
var topLayer = doc.activeLayer;//top selected layer
moveUpLayer ();
var upLayer = doc.activeLayer
var upLayerIDX = getSelectedLayersIdx ()
multiSelectByIDs (orgLayA[0][1])
var firstLayer = doc.activeLayer
if(upLayerIDX<lyrSelIDX[lyrSelIDX.length-1])
{firstLayer.move (doc.layers[0], ElementPlacement.PLACEBEFORE)}
else
{firstLayer.move (topLayer, ElementPlacement.PLACEBEFORE) }
var lastLayer = doc.activeLayer
for(var i=1;i<orgLayA.length;i++){
multiSelectByIDs (orgLayA[i][1]);
nextLayer = doc.activeLayer;
nextLayer.move (lastLayer, ElementPlacement.PLACEAFTER)
