Three things that I would change:
I wouldn't read the filenames into an array, I'd read them one at a time.
while ($_ = readdir(INDIR)) { ... }
I'd use next to skip the loop for '.' and '..'.
while ($_ = readdir(INDIR)) { next if -d || $_ eq '.' || $_ eq '..'; ... }
Finally (and most importantly) using backticks for commands where you're not capturing the output is wasteful as Perl collects up all the output and returns it to you - only for you to throw it away. Better to use system in that case. Or to use Perl version of the command where they are available - like using move (from File::Copy instead of mv).
Update: One more thing I've just noticed.
unless (-d $srcdir && -d $destdir ) {die "Error: $!";}
Not sure why you're including the value of $! in that error message. It won't contain a value at that point.
