Try changing:

Double quotes should also work as well as single quotes in this example. (I generally prefer single quotes when quoting constant strings.)
PS
I should have said why the quotes are needed...
The unquoted argument [:digit:] is a pathname bracket expression that changes to a list of files with the single character names :, d, i, g, and t if any such files are present in the directory where you run this command. If you run it in a directory where there are no files matching this pattern, the unchanged pattern is passed to tr as an operand. So, the reason it works sometimes and fails sometimes is the contents of the directory where it is run; not the script used to invoke it.
