Some shells, for example dash versions older than 0.5.4, need to spell a variable reference as '$N' rather than 'N' in an arithmetic expansion. In order to avoid the syntax error, we change the offending variable reference from 'i' to '$i' in function scramble.
There is nothing bash specific to this test script (and we shouldn't have any bash dependent test). Fix its shebang line.
