Bob - A few possibilities:

1 - 14.9 volts is at the limit of the "high" range for output voltage, unless the alternator is extremely cold (<20 degF or so).

2 - The alternator may not be develop rated output current under test - i.e. it has an open diode and is "single phased".

3 - The store clerk who did the test is an idiot.

Go ahead and stick the alternator on the tractor and try it out. If it charges 20+ amps immediately upon startup, then tapers down to 5 amps or less after running a while, the alternator is working fine.
