An explaination is probably this one: 
When you open a bottle of wine you hear a similar 'clunk' (if I understand 
the 'clunk' correctly). This has to do with the air column that vibrates 
within the bottle, the reduced air pressure .... The fingerholes of your 
bowling ball can be compared with that bottle. However, you only hear a 
'clunk' if the hole is well sealed by the ground, i.e. if it is just below 
the center of the ball (maybe it also has to do with the stiffness of the 
material, humidity...).
