This appears to be a misspelling or alternate spelling; the standard word is 'sorry,' meaning feeling regret or sadness about something.
If intended as 'sorry': from Old English 'sarig' meaning 'grieved' or 'painful,' related to 'sore.' The word evolved to mean feeling remorse or expressing sympathy.
If this is 'sory' rather than 'sorry,' it may be a variant spelling seen in historical texts or dialects, but modern English standardized on 'sorry,' showing how spelling reforms gradually eliminated variant spellings to create uniform communication.
