Spam 2.0 - Misspelled KEY in .mysql file

I'll confess I haven't looked to see if this is by design, but while looking over the .mysql file I noticed this:

DROP TABLE IF EXISTS spam_tokens;
CREATE TABLE spam_tokens (
  tid int(10) unsigned NOT NULL auto_increment,
  token varchar(255) NOT NULL default '',
  spam int(10) unsigned default '0',
  notspam int(10) unsigned default '0',
  probability int(10) unsigned default '0',
  last int(11) unsigned default '0',
  PRIMARY KEY tid (tid),
  UNIQUE KEY token (token),
  KEY spam (spam),
  KEY notspam (notspam),
  KEY probablitiy (probability),
  KEY last (last)
) TYPE=MyISAM;

Note that the word "probability" is misspelled as "probablitiy".
