Sorting an array on two computed fields

jesuashok has asked for the wisdom of the Perl Monks concerning the following question:

Please give me a Idea to sort the following array.

#!/usr/local/bin/perl

my @array = ( '1-1', '2-5', '1-10', '1-3','2-1');

print "value :" , $_ , ":\n" foreach ( sort @array );
[download]

Result:-

value :1-1:
value :1-10:
value :1-3:
value :2-1:
value :2-5:
[download]

But I want to have the following Result

value :1-1:
value :1-3:
value :1-10:
value :2-1:
value :2-5:
[download]

But I want the result should be in sorted order
