Trying to measure an ounce is nearly impossible by a measuring cup because 1 ounce is so very little. a shot glass holds (typically) 1.5 ounces, so you could fill one up 2/3s of the way to get a pretty accurate measurement... if your shot glass measures 1.5 ounces.. because they don't have a standard size!
Or, you could put a cup or shot glass or whatever small thing you want to measure, zero it out with the container/glass on the scale and then add your 1 oz. If I were you, I would put your coffee/espresso mug on the scale and measure directly in it and then add our espresso to the liqueur from there. Just zeroing out the scale with the mug on the scale before adding the liqueur.
BUT fluid ounce and ounce weight are not the same. For most liquids it is fairly close though - usually well within the measurement capabilities of your scale or measuring cups. But that is pretty easy to determine. Measure 2T, weigh it. If your scale is like mine (1/8th oz increments) it probably wont make a difference. In that case go with whichever is easiest. But berry is right, most shot glasses hold significantly more than 1 oz.
(OTOH many semisolids like jam are sold by the ounce (wt) and I know from cooking that 1 fl. oz of jam = about 1.5 oz.wt. )
