Following stevieb data representation I propose the following, somehow ugly, oneliner 
perl -e "print map{qq(val: $$_[0], idx $$_[1]\n)}sort{$$a[0]<=>$$b[0]}
+map{[$ARGV[$_],$_]}0..$#ARGV" 5 2 6 8 10 1 4 7 4 2 21 18 25 10

val: 1, idx 5
val: 2, idx 1
val: 2, idx 9
val: 4, idx 6
val: 4, idx 8
val: 5, idx 0
val: 6, idx 2
val: 7, idx 7
val: 8, idx 3
val: 10, idx 4
val: 10, idx 13
val: 18, idx 11
val: 21, idx 10
val: 25, idx 12
