An equivalent piece of code that does the same:
@array1 = @f.map do |linea|
  [ linea.to_i ]
end
@asort1 = @array1.sort

String#to_i ignores whitespace at the beginning (so you don't need strip) and 
will stop at the first non digit (so you don't have to remove what comes 
after the comma - it will just be ignored).

Though I wonder what the purpose of the @array1 variable is and whether it is 
intended that @array1 as well as @asort1 only contain one-element arrays.
In case @array1 has no purpose (other than holding the values to be sorted 
until they are sorted) and the one-element arrays are not wanted, this 
solution would work:
@asort1 = @f.map {|line| line.to_i}.sort
