I have tried both with and without the dollar sign in the naming convention.

Oh, you mean in the repository. Laserfiche clients only sort alphabetically. You would have to pad the numbers with leading zeros to the same length.

Workflow can do that with token formatting, if seeing documents named 000062.82, 000123.58, 013456.85 is acceptable to you.

That would work for us. I tried following the online help. but is is dropping the leading zeros. What tokens would I put in formatting

Could you post a screenshot of where you're doing the formatting? It should be in the activity that creates or renames these documents.

Here you go

That looks like regular expression. For formatting, you want to #s for the digits you want before the decimal point and use 0s to indicate how many digits you want after the decimal point. So, something like ######.00

Or ###,###.00 if you want to get fancy and add the thousands separator for readability.
