If I am asked to find the number of ordered bases of a finite-dimensional vector space over $\mathbb F_p$, what does that mean? Thanks!

It means the number of linearly independent $n$-tuples of vectors, if the space has dimension $n$. It is the same as the number of $n\times n$ invertible matrices over $\mathbb F_p$ because any two bases are related by one of those.

It just means that $\{a,b,c\}$ is counted separately from $\{a,c,b\}, \{c,a,b\}$ etc.
