What I'm thinking is that you could set up a 2D array and sort it on
the scores (element [1] of each sub-array).
Then you can extract the data you want.
You can do it using only arrays, which I think you said you wanted to do.
This is not a total solution, just an idea.

arr = [[1,7],[3,2],[4,9],[2,3]] # [horse,score],[horse,score] etc.]
arr.sort! {|x,y| y[1] <=> x[1]}
p arr #> [[4,9],[1,7],[2,3],[3,2]]
puts
p arr[0] #>[4,9]
p arr[1] #>[1,7]
p arr[2] #>[2,3]
puts
p arr[0][0] #> 4
p arr[0][1] #> 9
p arr[1][0] #> 1
p arr[1][1] #> 7
