Here's what's happening; a list in scalar context will return its last element.

@array[0..2] will return a list, and in @{}'s scalar context, the last element will be returned, which is the last array ref, that's why you get the last array's item 3 only.

Here's a workaround:

my @array=( [0,1,2,3,4],
            [25,26,27,28,29],
            [10,11,12,13,14]
            );
print @{@array[$_]}[3] for 0 .. 2;
