Select files from list AppleScript

select-files-from-list.scpt

set myValues to {"filename.ext", "filename.ext"}

tell application "Finder" to set fileList to files of target of front Finder window as alias list
set matchedFiles to {}
repeat with aFile in my fileList
	repeat with aValue in myValues
		tell application "System Events" to if aFile's name contains (contents of aValue) then set end of matchedFiles to (aFile as text)
	end repeat
end repeat

if matchedFiles ≠ {} then
	tell application "Finder"
		select matchedFiles -- you don't need to select files to duplicate them
		duplicate matchedFiles to (choose folder)
	end tell
end if

This is very inefficient and pounds the CPU. Much better off using something like the following in the command line:

cp ~/source/folder/{filename.ext,filename.ext} ~/destination/folder/
