Sort to subfolders based on last three letters of file

Question

I am working on a script i found that will take the contents of a folder and seperate them into sub folders based on the last three characters of the file name. They are named by user and month for example: Sam_Jan.xlsx. Here is what i have so far:
property nameList : {"_Jan", ""}
property destFoldersPath : {"/Users/ba/Desktop/DWI monthly/jan", ""}
on adding folder items to masterFolder after receiving these_items
repeat with tFile in these_items
set destFolder to my check_end_of_Name(tFile as string)
if destFolder is not "" then
tell application "Finder" to move tFile to destFolder with replacing
end if
end repeat
end adding folder items to
on check_end_of_Name(t)
set tc to count nameList
repeat with i from 1 to tc
if t ends with (item i of nameList) then return (POSIX file (item i of destFoldersPath)) as alias
end repeat
return ""
end check_end_of_Name
nothing happens when i run the script. my experience with applescript is pretty basic, but i feel like i need to put the source file in there somewhere but im not sure. the source file is a folder on my desktop called DWI Annual Report. Thanks for your help.

I prefer to use a bash script for something like this.
This script will look in the Folder "DWI monthly" on your Desktop.
It will look for the last 3 char in all files, and move to a Sub-Folder in "DWI monthly" with those 3 characters (i.e. Jan)  If the Sub-Folder does not exist, then nothing is done.  
If the file already exists in the Sub-Folder, it will be replaced.
This uses a do shell script , so this can be run in Applescript
do shell script "
for f in \"$HOME/Desktop/DWI monthly/\"*
do
    if [ ! -d \"$f\" ]; then
        x=\"${f%%.*}\"
        i=$((${#x}-3))
        if [  -d \"$HOME/Desktop/DWI monthly/${f:$i:3}\" ]; then
            mv \"$f\" \"$HOME/Desktop/DWI monthly/${f:$i:3}\"
        fi
    fi
done"
(BTW, your Applescript is a Folder Action (on adding folder items to), is that what you want?)
