well, your code looks surely good, but seems to be failing line count. on a simple ASP page of mine I get these results:

mine		yours
HTM	1	HTM	1
ASP	31	ASP	1
HTM	31	HTM	31
ASP	44	ASP	31
HTM	46	HTM	46
ASP	50	ASP	46
HTM	50	HTM	50
ASP	55	ASP	50
HTM	59	HTM	59
ASP	73	ASP	59
HTM	75	HTM	75

that is, it counts correctly for HTM blocks, but doesn't increment the line number for ASP blocks. I tried moving the line $line += ... before the push, but it didn't help.
