mootools conflict?

[rmuzzini]

very nice script.
it works flawlessly in simple sites.
whilst it seems having sort of conflict with mootools, beyond my comprehension & knowledges. :-)
i.e. if i link the scripts like it follows:

<script src="/cookieconsent.js"></script> <script src="/cookieconsent-init.js"></script> <script src="/mootools-core.js"></script> …

i get errors like
TypeError: ({}) is not a function
as if mootools tried to evaluate functions during the "modal" building (in "parseArguments" …?)
and, even if i use a "try…catch" statement to let the script goes to the end, then i get lot of unexpected lines in the categories tab ([Missing language object]), one for each "function" mootools catch.

anyone has a workaround for such weird behavior?
