    My suggestion:

     

    Previous month score for top scorer = 
    	VAR TopScorers = TOPN( 1, VALUES( Scores[name] ), CALCULATE(AVERAGE(Scores[Score])) )
        VAR PrevMonth = CALCULATETABLE( DATEADD(Scores[Date],-1, MONTH), LASTDATE( Scores[Date]) )
		  RETURN
CALCULATE( AVERAGE(Scores[Score])
		, TopScorers
		, PrevMonth
	)

     

    Note the TOPN function wil return several players if you have ties in your current selection. Hence the average calculation.

     

    Also, in case several months/dates are selected, I take the last one and calculate the previous month for this date.

If there is a filter ="Alice" then it should return the measure value of "Alice" for the month of Feb.

If no filter is present then it should give the Highest scorer's previous month value, in this case it will be "Sam's" Feb value.
