From what I've read, having a deficit in social communication is a core definitional symptom.

"[The DSM-V states] that an autism diagnosis requires persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following: deficits in social-emotional reciprocity, in nonverbal communicative behaviors used for social interaction, and in developing, maintaining and understanding relationships."

Exact text of the DSM-V on autism:
Diagnostic Criteria
A. Persistent difficulties in the social use of verbal and nonverbal communication as manifested by all
of the following:
- Deficits in using communication for social purposes, such as greeting and sharing
information, in a manner that is appropriate for the social context.
- Impairment of the ability to change communication to match context or the needs of the
listener, such as speaking differently in a classroom than on the playground, talking
differently to a child than to an adult, and avoiding use of overly formal language.
- Difficulties following rules for conversation and storytelling, such as taking turns in
conversation, rephrasing when misunderstood, and knowing how to use verbal and
nonverbal signals to regulate interaction.
- Difficulties understanding what is not explicitly stated (e.g., making inferences) and
nonliteral or ambiguous meanings of language (e.g., idioms, humor, metaphors, multiple
meanings that depend on the context for interpretation).
So, I'm not a diagnostician, but if you have above average ability to read social cues, then that sure sounds like it excludes a diagnosis of autism.
If anyone has information from an authoritative source that explicitly says otherwise then I'd be interested to see it, thanks
