Wpuld say that they are most likely to be tiger barb eggs. As you say, the mollies are live barers, and the corries are egg placers (lay semi-adhesive eggs all together on a chosen spawning site). That is assuming they are eggs. I don't recall ever seeing any eggs looking like that. Then again, I have never bread barbs.
If they are indeed eggs, scoop them into a cup, and transfur them to a qt tank. You need a air driven box filter, to prevent the fry beeing sucked into the filter. A higher-than-adverage temp will boost growth, however it also facilitates the quicker spread of disease, should an outbreak such as whitespot or velvet occur.
Congratulations and good luck raising them
