Top 5 High score script Needed (800L)

I'm in need of a full permissions script that will keep track of the top 5 scores for a game I'm developing in a unique way.

*Auto sorts the top 5 scores Highest to lowest.
*In the case of the tie, the newer score gets put ahead
*Only retains one unique person on the list. That is, if you placed third, and then placed first, your 3rd place score/name would be removed from the list entirely and just your first place score/name would be in the list.

example:

Player A: just got a score of 7.

John Doe: 10
Jane Roe: 9
Joe Doe: 8
Player A:7
Jane Doe:6

Player A: scored a new score of 11 so his old score of 7 is removed.

Player A:11
John Doe:10
Jane Roe:9
Joe Doe:8
Jane Doe:6



*input to the scoreboard script will be a string broadcast on a secure channel in the format of "Resident Name//Score"
*Output can be as either a list, string, or llSetText().
*The score checking/sorting needs to work with both integer and float values for the input.

I'm asking $800L (Negotiable) for such a full perms script which will be used in a marketed product.

I can make you such a script for around 800L, IM me inworld.
