Could you put an ISBLANK formula in column B [=ISBLANK(A1)] and then change your formula to:
=Match(True,B1:B100,0)

{=MATCH(TRUE,ISBLANK(A1:A100),0)}
Note: This is an array formula which must be
entered using the Control+Shift+Enter key
combination. The outermost braces, {}, are not
entered by you -- they're supplied by Excel in
recognition of a properly entered array formula.
Just for humor value (if any), when you get started down the wrong path, disasters like this occur:
=LARGE(((ISBLANK(A1:A100))*(ROW(1:100))),100-COUNTIF(A1:A100,"<>"&""))
I hate when that happens.
