Script for moving $ to end of numbers

A while back I asked this question "I have an english indesign file that was translated to french.  The last thing to be changed are the dollar values.  In english they appear like this $1,200 and in french it needs to have a space followed by the dollar sign at the end of the number and with a space instead of a comma like this 1 200 $".

I was ecstatic when I was given a 2 part solution.  The first was from @uniqued_tol (thanks again) which formatted all numbers with more than 3 digits.

Find: (^\$)(\d+)(,)(\d{3}) Change: $2 $4 $1

I then ran the script by @Obi-wan Kenobi (thanks again) which formatted the remaining numbers that were 3 digits or less.

Find:  (\$)((\d+,)+\d+) Replace by:  $2~s$1

I now have another large book to format but this time there are decimal points so these scripts are not working.  I need a number like this $2,300.99 to be formatted to look like this 2 300,99 $  I have numbers with digits as small as $10.00 up to $4,500.99

Once again any help would be greatly appreciated.
