Save with different extension

[Magnus von Brömsen]

Hello

I want to save a text-file with different extension (on Windows) – if 
this is possible (?). So, I have this script:

on mouseUp
   ask file "Save order as:"  with filter "Excel file,*.xls","Word 
file,*.doc","Plain text,*.txt"
   if it is empty then exit mouseUp
   put field "OrderData" into url ("file:" & it)
end mouseUp

I can choose between the different types, but I have to manually write 
the extension to the filename to have the file associated to the 
application.
Can that be done in the script?
