For what it is worth after a bit of googling, most resources list variables
as the first scope and exclude arguments altogether. However I did confirm
that arguments is searched first with this quick test:
<cffunction name="outputBlah">
<cfargument name="Blah">
<cfoutput>#Blah#</cfoutput>
</cffunction>
<cfset Blah = "variables">
<cfset outputBlah("arguments") />
When I run that code, the string "arguments" appears on the page.

Sophek , I just double checked and my frail memory was failing me it

Here is the order of precedence:
1. Arguments
2. Variables
3. CGI
4. Cffile
5. URL
6. Form
7. Cookie
8. Client
