It hasn't been running on CFMX for years, though, right? Was it on CF 5 or a
previous version earlier?

In CF 4 and earlier, the values for CFID and CFTOKEN were always numeric, I
think. In that case, the above code would work fine. In CF 5, an option was
introduced to allow the use of a UUID for CFTOKEN, instead of an integer.
That's what you're showing in your error message. In CF 5, to enable this
option, you had to edit the registry (or cf.registry on Unix). In CFMX, this
option is exposed in the CF Administrator.
You can probably work around this by changing your code to look like this:
<cfif StructKeyExists(Session, "spanish1#cfid##cftoken#")>
