@combo holds three (probably undefined) values, not the contents of the arrays. Something like the following would work better for you:

for (0 .. $#skuid) {
    print "SKUID: ", $skuid[$_], "\n";
    print "NAME: ", $name[$_], "\n";
    print "PRICE: ", $price[$_], "\n";
}

You might want a different datastructure, though, so take a look at perlref and perldsc. A list of lists would do the trick nicely.
