One Value Sorting within an Array

System

I want to sort on only one variable within an array instead of all items.

A simplified example is shown below - I want to sort on $field1 only, and not have additional sorting done on other fields/replicant values etc.

push(@SortedDCRs, $field1, $reportname, $month...etc);
...
...
foreach (sort @SortedDCRs) {
($field1, $reportname, $month...etc) = split(/\|/,$_);
}
