Echoing Terry Ryan's comment CF9 has a much more complete cfscript implementation. - kevink
Careful! the Open Blue Dragon ColdFusion implementation doesn't offer cfscript, so if you use it you're tied to Adobe. - O. Jones
@Ollie Jones, no, he is not. He can use Railo, which has full-script CFC support. - Mohamad
@OllieJones: yeah it does. Just tested on OpenBD 3.0 - Adam Cameron
@CFUser, given you're getting differing answers for different CFML engines, it might help if you tag this with the correct engine / version? - Adam Cameron

ColdFusion 9 added the "writeLog" function which allows you to do this. http://help.adobe.com/en_US/ColdFusion/9.0/CFMLRef/WS48D04B65-0694-44e9-9E35-F9D7C9152B6C.html

In Lucee/Railo you can use cflog in script by removing the angular brackets and the "cf" prefix, so you can write

<cfscript>
  log text="some text" file="logfilename" type="information";
</cfscript>

this is equivalent to

<cflog text="some text" file="logfilename" type="information">

Unfortunately on versions of ColdFusion prior to CF9 there isn't. However, what you can do is map a UDF to cflog:

<cffunction name="doCFLog">
   <cflog attributeCollection="#arguments#">
</cffunction>

inside your cfscript call the doCFLog function with the same attributes as you would cflog

eg. doCFLog(text='sometext', type='warning',application='yes', file='mylog');

Note: its not a good idea to call your methods/udf etc the same name as an existing function or tag, hence not calling the function "cflog" or "log"
