In principle, no: so long as it's above its freezing point, by however
small an amount, you don't get solid forming.
In practice, that's a small margin and you'd want to watch issues like
impurities in the propane (commercial "propane" contains significant
amounts of propylene, butane, etc.) and variations in temperature within
the tank.
OT but apropos:
can one utilise the paramagnetic properties of LOX in rocket context?
Possible in theory, especially for controlling where the liquid goes in a
partially-filled tank in microgravity, but I don't know of any actual
attempts at it.
