bug#7305: sort command not working in version 5.5 as it did in 4.7

[Michael Warnock]

Hi -- We are testing RHEL 5.5 and we noticed that the below command is not
working in 5.5 -- It works in 4.7
I did notice that the version of the sort command is different between
versions, but I didn't expect it to break.

Am I just using it incorrectly in 5.5 or could this be a bug.

Thank you very much!
