It is treating the numeric digits not as integer numbers but as characters. You need to have the value as:

HMD001,HMD002,.....HMD010, etc.

You have to provide sufficient space for the digits to increment. You can alternatively build the index as follows (assuming the field name is mykey):

INDEX ON LEFT(mykey,3)+PADL(SUBSTR(mykey,4),4,"0") TAG mykey
