ASCII ordering with sort command

Hi,

When I use the "sort" command, the results are NOT coming back in ASCII order. I thought the default for this command was to return results in ASCII order.

To illustrate,

myfile contains 3 names:
Ann
$Brad
Carrie

Here is a transcript of when I use the sort command:

[root]# sort myfile
Anne
$Brad
Carrie

However, this is wrong (I think). The correct ASCII ordering of these names would be as follows:

$Brad
Anne
Carrie

...because the $ symbol precedes alphanumberic characters in an ASCII ordering.

How can I alter the sort command to properly ASCII order the names in a file?

Thank you!
