Are the region numbers sequential, or discontiguous?

If sequential: 

my @StatsArray;
push @{$StatsArray[$RegionNum]}, {
  AR  => $AR[$RegionNum],
  BCR => $BCR[$RegionNum],
};

[download]

If sparse, this: 

my %Stats;
push @{$Stats{$RegionNum}}, {
  ...
};

[download]

Then you could do this: 

my @sorted = sort { $a->{AR} <=> $b->{AR} } @{ $StatsArray[$RegionNum]
+ };

[download]

...for example.

It might be that you're getting to the point where a database would scale better though. Another approach might be to just build a binary tree, maintaining nodes in sorted order. This allows for relatively inexpensive inserts and searches. But it does sound like you might need the scalability of a DB approach.
