Is this what you are trying to do?

<cfset lstReport= & quot;BioDraftReport,CacheDraftReport,CaseFileDraftReport,ChemicalDraftReport,DTK
DraftReport,DetonatorDraftReport,ElectronicDraftReport,IDFDraftReport,IEDDraftRe
port,MFTERDraftReport">

<cfset objRandomReport=ArrayNew(1)>

<cfset objRandomReport=ListToArray(lstReport)>

<cfset ArraySort(objRandomReport,"textnocase","ASC")>

<!--- random number b/n 1 and length of list/array --->
<cfset reportName=objRandomReport[RandRange(1,ArrayLen(objRandomReport))]>

<cfoutput>#reportName#</cfoutput>
