A writing system is (usually) language-dependent, a script is not, although some scripts have been used exclusively (or prominently) in a single writing system with a single language. So definition (1) of ‘grapheme’ would be appropriate for linguistics, (2) maybe for typography and computer science, but it’Í extremely vague.
