arcgis desktop - Why does inline variable output overwrite occurs with Reorder fields tool?

I am trying to use this Reorder fields modelbuilder tool but for some reason the inline variable (%name%) for the output gets overwritten with each file pass until the last one. Otherwise it works fine, however, I need to process hundreds of shapefiles and rearrange the field order.

Any help or corrections would be greatly appreciated.

I've attached an image from the modelbuilder I am currently using. Here's the script:

import os,string,sys


try:
    import arcgisscripting
    gp = arcgisscripting.create()
except:
    import win32com.client

    gp = win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1")


FC_In = sys.argv[1]
NewOrder = sys.argv[2]
FC_Out_WS = sys.argv[3]
FC_Out_Name = sys.argv[4]

strFields = gp.listfields(FC_In) 
strNewOrder = NewOrder 

Layers = [""]

# Get Field Collection into List
Fields = gp.listfields(FC_In) 

NewOrder = string.split(strNewOrder,";")
print Fields
print NewOrder

x=0 #NewOrder enumerator 

y=0 #Layers enumerator (first)

# Cycles through the input feature class creating field collections
while x    Fields.Reset()
    Field = Fields.Next()
    while Field:
        FieldName = str(Field.name)
        if x            Layers[y] = Layers[y] + FieldName + " " + NewOrder[x] + " VISIBLE"

            x=x+1
        else:
            Layers[y] = Layers[y] + FieldName + " " + FieldName + " HIDDEN" 

        Field = Fields.Next()

        if Field:
            Layers[y] = Layers[y] + "; "
            FieldName = str(Field.name)
        else:

            print Layers[y]
            Layers.append("")
            y=y+1
            Layers[y]=""


# Use Field collections to create Layers with proper order until all fields have been used
z=0 #Layers enumerator (second)
LayerList = ""
for Layer in Layers:

    if Layer <> "":
        if LayerList <> "":
            LayerList=LayerList + ";"
        LayerList=LayerList + "Layer" + str(z)
        print LayerList
        gp.MakeFeatureLayer(FC_In, "Layer" + str(z),"#","#",Layer)
        gp.addmessage(gp.getmessages()+ "\n")
        z=z+1



#Collect Info about Input Feature Class

fc_in_sr = dsc.spatialreference

# Create new empty Feature class with desired fields 
try:
    gp.CreateFeatureClass(FC_Out_WS,FC_Out_Name,fc_in_stype,LayerList,"#","#",fc_in_sr)
    gp.addmessage(gp.getmessages()+ "\n")
except:

    gp.addmessage(gp.getmessages()+ "\n")



# Append Records to new feature class
print FC_Out_WS + "\\" + FC_Out_Name
