sort returned only one line in bash

I have a variable which look something like this:

param="David Salad 100\nMark Fruit 440\nNoam Chicken 440"

I need to sort it according to numbers and then according to Alphabetic order so the out put should be:

Mark Fruit 440 Noam Chicken 440 David Salad 100

I tried to write the following line:

temp=`echo -e $param | sort -srnk3`
echo -e $D

But the out put is "Mark Fruit 440 Noam Chicken 440 David Salad 100" The sort doesn't print any \n 's even though I thought it should.

The sort works

$ param="David Salad 100\nMark Fruit 440\nNoam Chicken 440"
$ echo -e $param | sort -srnk3
Mark Fruit 440
Noam Chicken 440
David Salad 100

you just have to quote the variable ("$temp") to see the newlines

$ temp=`echo -e $param | sort -srnk3`
$ echo "$temp"
Mark Fruit 440
Noam Chicken 440
David Salad 100
