I agree with Anil... Store it as an integer, not as as String. That will
help for the comparison (be carreful with negative values comparisons.).
Worst case, run a MR job to convert them.

The only way I was able to do negative numbers was to create a new
WritableComparable that took signed-ness into account, but that involved
deploying the class to the cluster.

OK, let's say it is stored as an integer, how to compare then?
As Jean-Marc pointed out, negative numbers is greater than positive ones using
ByteArrayComparable.

Looks like you should be able to do so by passing your own comparator to:
public SingleColumnValueFilter(final byte [] family, final byte []
qualifier,
final CompareOp compareOp, final ByteArrayComparable comparator) {

That requires creating my own ByteArrayComparable class and deploy to all
servers, right?
My company doesn't want to customize hbase, hence is not an option to me.

Sure, try using the BinaryComparator. For example,
BinaryComparator c = new BinaryComparator(Bytes.toBytes(200));
System.out.println(c.compareTo(Bytes.toBytes(201))); // returns -1

What would happen to this ?
System.out.println(c.compareTo(Bytes.toBytes(30)));

BinaryComparator wont work for your case.
But, I am wondering why you would store an Integer as String when you want
to do numerical comparison?
