Results are in! The "most elegant" solution, to me (subjectively) was Tom's. It was short, 2 lines, 2 CF functions, easy to read and figure out what was going on. Dare I say pretty?
<cfset reResults = reFind("numPageID=([0-9]+)",CGI.HTTP_REFERER, 1,true)>
<cfset theNum = mid(CGI.HTTP_REFERER, reResults.pos[2],reResults.len[2])>
Marlon wins for least amount of characters. Concise, efficient but
hard for me to follow the regex. Definitely a guy's solution. He
could have made it one character shorter by using "gettoken" instead
of "listgetat"!
<cfset pagenum =
listgetat(rereplacenocase(CGI.HTTP_REFERER,"[(?|&)]*numpageID=(\d*)","#chr(10)#\1#chr(10)#","all"),2,chr(10))>
Chris, Rick and Anthony's solutions were just about the same. Logical
and easy to understand.
<cfset ReferrerQS = ListLast(CGI.HTTP_REFERER, "?")>
<cfloop index="eachParamSet" list="#ReferrerQS#" delimiters="&">
<cfif ListFirst(eachParamSet,"=") IS "numPageID">
<CFSet MyNumPageID = ListLast(eachParamSet,"=")>
</cfif>
</cfloop>
Mine was the worst, which is why I submitted this to the group to begin with!
Thanks for playing!

Whoa! I just got back to this! First thing - Settle down boys! I guess since I posed the question I get to judge. I'll go through all the submissions, review carefully, and come back with a report and my version of "elegance". To clarify, it was Tom who asked for the "Henny Youngman" - one liner.
