Hbase: Is possible to filter by integer value if the value is saved as string?

[Frank Luo]

I don't think it is possible, but would like to confirm with smart folks out 
there.

Supposing I have a cell storing an integer but in string presentation. For 
example, here is how I put a value of 200:

        put.add(family, qualifier, Bytes.toBytes("200"));

Now, I want to scan with a filter that only return if the value is larger than 
250. Is that possible?

Thanks in advance
