If the job were public relations or something, this would be understandable to me. But I've known many people who were extremely competent in a field, but didn't really care about things that didn't interest them (such as job applications). You should look at these people's portfolios, not dismiss them over some assumption about how their trivial spelling errors speak to their inner character. If these job applicants have a responsibility to be professional in their presentation of their skills, why don't you have a responsibility to be professional in your appraisal of their applications? These are completely petty reasons to drop a resume, akin to "they showed up at the interview without a tie."
