As a suggestion, try this:

my @zips =  grep { /\.zip$/}      @uploads;
my @meta =  grep {/zip\.meta$/}   @uploads;
# "Your Mother" pointed out that I had meta/$ instead
# of the correction shown. .meta$/} Oooops.

print "zips= @zips\n";
print "zipmeta= @meta\n";

Update: Something like this might work.

foreach my $upload (@uploads)
{
    if   ($upload =~ m/zip$/i)
    {
        print "I GOT A ZIP\n";
    }
    elsif ($upload =~ m/zip\.meta$/i)
    {
        print "I GOT A META\n"
    }
    else
    {
        print "I got NADA"
    }
}
