First, Perl is not C or FORTAN or ASM.
This kind of thing:
for ($i=1; $i lt $n; $i++){....}
is an extremely "rare duck" in Perl!
These i-n (INteger) variables just aren't needed in most cases.

Perl uses a variant of QuickSort and for almost all of your sorting, you should too! This is normally faster than SelectSort. Use the power of the language!

Re-coding your program, 

@a = (8,5,2,4,88,1,5,4,3,2);
@a = sort @a; #same as @a = sort{$a <=> $b}@a;
              #because only digits not alpha/digits
print "@a","\n";
#prints: 1 2 2 3 4 4 5 5 8 88
