"~" seems like a strange character to see in a version number so if upstream has not specified how the version number is to be written, then I would suggest a dash (1.2.0-beta1) or no separator (1.2.0beta1 or 1.2.0b1).

AIUI, the tilde affects version comparison in the dpkg world so that
1.2.0~beta1 is considered older than 1.2.0. Our vercmp proc doesn't
support anything like that.
