Tom has apparently abandoned support for new
versions of ACR in his script. You can make the script not complain about
newer versions such as ACR 4.5 (or now ACR 4.6) if you open the jsx file in a
text-editor or the ExtendScript Toolkit 2 editor and do a
search/'replace operation to change all four occurrences of "4.1" to "4.5" or
whatever version of ACR you are using.

However, instead of using this script with LR 2 and
ACR 4.5 and soon ACR 5.0, the recommended course of action is to use the DNG
Profile Editor to create custom camera profiles which instead of taking 10s of
minutes take only a few seconds.
You can create a general-purpose dual-color-table
profile like comes with ACR or you can create lighting-scenario-specific
profiles. Personally, I have created both a general purpose profile using
two shots of my CC, one in incandescent (close to 2850K) and one is hazy
sunlight (close to 6500K) or D65 lighting as well as several lighting-specific
profiles where both color tables are computed from the same RAW.
The DNG Profile Editor is available from Adobe Labs
in addition to some beta profiles for different situations: landscape,
portrait, faithful, neutral, etc:
