Well, I would have thought that URL.somefield is still
"value1,value2,value3" but that's apparently not true. Hmph.
You could treat the string as a list with & as the delimiter and use a loop.
<cfset newstring="">
<cfloop list="#CGI.QUERYSTRING#" index="i" delimiter="&">
<cfif ListFirst(i,"=") EQ "somefield">
<cfset newstring=ListAppend(newstring,ListLast(i,"="),",")>
</cfif>
</cfloop>
